[Idea] Super Antenna

I was wondering seen as how we have an external antenna couldn't you build something that attaches to it and improves phone signal or make a cantenna? Any suggestions on how to do this?

I don't know how much help this will be but I love the DIY spirit so here are some of my ideas.
Connecting to the existing antenna array could be achieved by attaching wires into the existing contact points in the back plates, then route through the camera lens opening out of the phone. The wires will have to be thin so that is something to consider. i.e. more fragile at longer lengths.
The new antennas could be based existing off the shelf parts or from existing DIY projects for each respective technology, but AFAIK you cannot use a single cantenna type device. Due to the different frequencies used for WiFi/Bluetooth vs. GSM vs HSPA+. I am unsure about how many you will need as a minimum or if there are special power requirements between the different technologies involved here.
Power will have to be another consideration. Not 100% certain, but I believe to get these "super" antennas to be truly super, you will need to increase the power to them. This will of course lessen battery life. So that would be another consideration. This mod might spawn a separate battery mod/swap.
I am not sure if this is cost effective or not, but DIY doesn't always consider cost. Of course if you are planning on using this to power some autonomous super killer robot, that can record in 1080P, and stream back live VGA video using the hardware built into the phone this could work out pretty well.

What if you somehow took gold wiring like on the connectors, attached it to the connectors and ran it along the inside of the back cover?

if this does improve reception htc should replace all our back covers, with this^^ already done.

I think the one above the camera hole is for wifi because I saw a youtube video of a guy that took some tin foil and stuck it in the hole on the phone where that connector would make contact and it gave him a really strong wifi signal. He took out the foil and the signal dropped. So I'm thinking that the connector on the top is wifi. The strange thing is I also have an unbranded euro/asian sensation and it has one less connector than the TMO us one (but uses the same mobile bands/radios) and when I use that cover on my US sensation there is no signal difference. So I really wonder what that extra one is for, since I have noticed no signal difference when using one over the other on the US phone.

Hey guys Ive been giving this some serious thought and here are a couple of my ideas on this....I am looking for some serious Beta testers for my ideas, there is no money compensation for testing just fame and prestige......PM me if your intrested in beta testing for me..hurry I have a feeling a lot of people are gonna want in and space is limited.

Maybe T-Mobile uses AWS bands for HSPA+? I'm not sure if that's even possible, but I don't know much about that stuff.
Anyway, I believe the antennas are:
Above the camera: Wi-fi
Below the camera: BT? (correct me if I'm wrong)
On the bottom cover: Mobile network
And @joemm Lmao!

No, My Asian sensation has the same bands as my tmo sensation. It has the AWS band and gets the same download speeds as my TMO version. If it wasnt the same bands I wouldnt even get 3g, I would be stuck on edge. Tmo's 3g and 4g(HSPA+) run on the same frequencies. So if you have a phone that doesnt have the AWS band and the phone supports 3g and 4g you will only get 2g speeds. I believe All the the sensations first released had the AWS bands. I think only now are they starting to release versions with different bands. I know a while back a sensation passed through the fcc with att bands. Maybe those are the ones we are seeing popping up on Bell now?

Hmm, not sure how good this idea would be, but it's worth a shot
I'm thinking as the antenna has to be of a specific length to work, this length is determined by the frequenzy of the signal
Here is some examples : http://www.air-stream.org.au/wavelength

This helps alot. I guess the only thing to do is to make an extended anttena and keep sticking it on contacts till i get better signal lol

I was toying with this idea after I noticed the sub-par data connections I've been getting. Maybe there will be a new radio after we get s=off. Here's hoping...

I have a new back cover coming and I might due some experimenting with the old one.

ive stuck tin foil in the back of it touching th ebottom two connecters and ive never suffered from death grip since , going on 2 weeks now :0

It should be possible if we could get a flexi pcb that we stick inside over the exisining connections and route outside and fold around that sticks down. I dont think we need more power, just a increased area. Should be easy to do.

[Q] Galaxy Tab 2 7 Wifi antena issue? Death Grip

Similar to iPhone 4, the wifi bar drops when I grab lower left corner in portrait mode. It doesn't seem to drop the connection completly but the bar goes down from 5 to 1..
Does anyone have this issue or could it be specific to my unit? Ready to swap if so

Crap! You are right! Happens on mine and on my buddy's tab.

It is on the same side with sd card slot. Assuming that wifi signal goes down by grabing where the serial number sticker is in the picture. If it is a device specific issue I will return mine and swap it.
Pls share your story to figure if it is a design issue that all sgt2 7 have this flaw.

Thanks for the suggestion. w/o death grip: -40dBm. with death grip -70dBm.
This confirms it and the signal drop occurs in a couple of seconds.

My tab has *EXCELLENT* wifi reception... when I hold it in portrait - upside down.
Only slightly less better in landscape either right side up or upside down. Seriously. Better even than my Droid X.
They had to put the antenna(s) somewhere. Leave it to an engineer to pick the worse location.

Thanks and it justifies the swap to new one. I am actually glad to hear that it is not an universal issue.
Sent from my GT-P3113 using Tapatalk 2

The signal drops if I hold it along the lower left side in portrait, but I don't loose connectivity. While they could have put it somewhere else, the best place would be where the power and volume buttons are, but the buttons probably prevented that. If they put it anywhere else, there would be an issue with poor location when being held, or loosing signal while being held.

Swapped with new unit and the problem does not occur at the same level. The signal strength does fluctuate but within a smaller range than the previous one.

Good to know. Droping almost all signal is crazy... Mine drops one line; that is to be expected at some point.

My tab also suffers from this death grip problem
Connection strength drops from -52 to -72 when I hold it the bad way.
Couldn't they better isolate the antenna ?
Otherwise it works perfecly fine.

They could. Right up to the point where it doesn't work at all.
RF layout and design is a fickle thing, where everything becomes a series of trade-offs. Personally, I'm amazed that works as well as it does.
For a living, I do PCB layout and manage/maintain an ECAD library. I recently put a part in the library - WiFI/Blutooth antenna chip. It's a tiny, really tiny thing with the inputs on opposite ends. At the time, I notice the datasheet said both inputs were GROUNDED. (?!?) I brought it up to the tech that submitted it - who called the manufacturer and we determined it was not a mistake. I did the layout, the boards were fabricated and assembled, and it works perfectly. It's just a mystery of modern RF technology.

I've spent some time with Samsung support. This is what they had to say:
Visitor: It sounds to be a hardware issue at least in my opinion... something with the antenna placement, bad isolation or something...
Samsung: Thank you for holding.
Samsung: Thank you for bringing the issue to our notice.
Samsung: I will make sure that the concerned department hear regarding this issue.

Since everyone sees this as a huge problem, where do you want to put the antennae that it wouldn't see a drop in signal during use? Put it at the top left, and it's going to be on the very bottom during landscape use and likely see issues. Put it on the top and you loose signal during landscape use, plus you have to deal with the headphone jack. Put it on the bottom and you need to move the USB connection and speakers, and you would deal with signal loss during landscape use. Put it on the bottom right, and you loose service the same as you do now. Put it on the top right, and you have to deal with the power/volume buttons and the IR blaster. So where does everyone want to put the wifi antennae then? A dongle that plugs into the device?

Be a left handed person
At least, top left side is less touched than other place unless move the power button and put WiFi there...
Anyways the intention of OP was to figure out if it is a design issue or a flawed device case. At last we know what it is and have some piece in our mind by admitting it as it is.
Knowing that Kindle fire has a similar form factor and use scenarios, I wonder if Kindle fire also shows the same death grip case.
Sent from my Lumia 900 using Board Express

If it were an issue with the case, you wouldn't see any change in signal, or you would have terrible signal all the time. It could be considered a design flaw but it is likely a design compromise. It could also be that they tried to put the wifi antennae elsewhere, but found that it had the best performance in the current location.

Help:htc one x inside repair !

So i have and issue, here i have attached pictures with :
1. broken connection line. Question - is this repairable ? or it can only be replaced and where? can it be soldered ?
2. broken lcd socket. as you can see in the image the socket has one line broken. does this affect a lot ? or it is not a big deal ?
waiting for reaplyes.

i'll give it a shot for your answers -
the first one - the ripped flex cable - is not repairable - has to be replaced. As for where you can have this done - I don't really know. If you are lucky its just a cable that plugs in on both ends - if you are unlucky, its connected to something expensize on the other end and you can't just replace the cable - I don't really know, haven't taken my HOX apart. You can see the plug on the one end though - maybe get some pics of the other end of the cable? As for soldering - probably not - if it's only a single layer flex there's a small chance, but you would have to be a really good solderer to solder it. If it's a multiple layer flex cable, then there's pretty much no way.
The 2nd one - the broken lcd socket - that really depends on what ithe broken pin was used for. I'm not familar enough with the hardware inside the HOX to tell you, but there's a chance that its not needed or not used or used for something that's not important (like ambient light detection) and with it not working your phone may still work. That being said, it may also be used for something important, and without that one pin your screen won't work. Without the schematics and/or pinouts for the phone, it's hard to tell. Maybe someone here with more knowledge than I have will be able to help you with that more.

Most the ribbon cables you can purchase online. Google around. The pin broken is going to matter. Thats your main board and even if u can fibd one its going to be extremeky expensive. Start searching around for a broken one you can buy for parts or something.
Lastly, how in thee hell did you do that much damage disassembling it?? Omg lol

well the ribbon part goes from power button, so thats why i was worried ;/. and going to light sensor, but dont know where it goes after, so it looks like one way , becouse comes out of power button, so it might be a chance of me to stick it together ?

Wifi Antena - Double/Change Camera

Hi, yesterday i open my gtab and i saw the wifi antena its very small
Is there any way to change it? or amplyfi the wifi signal by changing it?
I was thinking changing for one of these:
http://www.ebay.com/itm/1pc-New-Lap...ectional_Network_Antennas&hash=item5ae928d096
http://www.ebay.com/itm/1pc-Laptop-...ectional_Network_Antennas&hash=item5ae6213b5f
http://www.ebay.com/itm/U-FL-Mini-P...ectional_Network_Antennas&hash=item4cf5ef6d82
I think this its the best:
http://www.ebay.com/itm/U-fl-Laird-...ectional_Network_Antennas&hash=item416946edf8
Problem solved (Antenna) i will get one OMNIDIRECTIONAL ANTENNA 9bi and try to get inside the tablet, i will post pictures by request.

anyone?

A solution for you would be this:
buy one of these (dont have to use fleabay of course, but it must be IPX to RP-SMA)
http://www.ebay.com/itm/U-fl-IPX-to...824?pt=LH_DefaultDomain_0&hash=item4a9fb5aa28
drill a hole on top/side to fit perfectly and screw it in, the ipx end will attach (snap on) to the motherboard.
then you can buy one of these:
http://www.ebay.com/itm/7dbi-2-4GHz...ectional_Network_Antennas&hash=item45fbc0cf30
or you could even get one of these:
http://www.ebay.com/itm/Netgear-Pro...ectional_Network_Antennas&hash=item415fa80efb
this one would not be portable but you would have a great signal!!
your only requirements are the IPX connector and an RP-sma adapter if the antenna you buy does not have an Rp-sma connector
Our antenna is like the second one I linked, just way smaller, probably 2 or 3 dbi.
In terms of signal, every 3dbi is a double in gain, so a 7db would be double or triple stock antenna strength
You have the right idea, but anything less than 5db would be a waste of time, you wont notice much, and the patch antennas are directional. The external rabbit ear type will receive from any direction
to mods: I am not a vendor and I hope linking to fleabay is not against the rules. I will change if needed.

so, what about your antenna? did you see any difference from stock antenna?
i dont want to have any external antenna, because i use it most of times with some of my clients, and having some external antenna takes the "stylish" thing to the g-tablet, i have even consider to buy some carbon fiber for the back
so you say that the last option i consider (the black internal antenna rectangle) will be useless? or worst than the stock antenna?
can you send me a picture of the work you made with your tablet?

NO, the STOCK antenna is 2 or 3 dbi. If you upgrade to a 4dbi like the one you linked to, you will not notice a difference, but if you went up to 5dbi or 6 or 7, you will notice an improvement. They make patch antennas which may fit inside our tab, but if you do not get at least 5, it is a waste of time. I have not changed mine, but I have a lot of PC experience getting people wifi from long range. I have even set up a connection two miles away using a 24dbi dish from an mmds system. I am just saying that wifi reception is based on signal level, measured in DB, and every +3DB is equal to double the reception strength. If you go from our STOCK 3DBi to the one you showed, you will be mad that your signal is the same. go to atleast 5, and you will see a difference. Some people think their wifi is crappy because they do not realize our STOCK antenna is directional, and if facing the wrong way, signal will be weak. I only suggest the external antenna for a more noticeable improvement. You will have to choose style over strength or vice-versa.

Thats great info! i made a research
and as you say, omnidirectional will be best option
so, instead of having an EXTERNAL antenna as you suggested
why no put inside the tablet?
will work the same right? and will be omnidirectional , right?
as the space inside gtablet with the both plastic covers isnt that much
i tought this its my best option:
http://www.ebay.com/itm/2-4GHz-7dbi...090?pt=LH_DefaultDomain_0&hash=item3f05ccd302
+
http://www.ebay.com/itm/RP-SMA-fema...761?pt=LH_DefaultDomain_0&hash=item4ab4023a39
I will just dismantle it, and make it happen inside the tablet (the plastic cover around antenna its useless right?its just for protection? since will be inside tablet no need protection, right?)
another options are this:
http://www.ebay.com/itm/Genuine-Lin...ectional_Network_Antennas&hash=item1e677a7dd1 (this its directional only, will be that bad?) (but its ufl/ipx :good
http://www.ebay.com/itm/Dual-Band-2...ectional_Network_Antennas&hash=item20c639d4fb (cheapest but 1 dbi less, its that much difference?)
http://www.ebay.com/itm/7dBi-Linksy...ectional_Network_Antennas&hash=item1e6e6818b5
As your an expert in this specific area, what do you suggest me from this options?
I know Linksys its a great company for wireless solutions, right?
but ,chinese omnidirectional 7dbi vs Linksys directional 7dbi
What you think will be better for my specific case? I know its hard, since its omni vs directional antenna, and also no-brand vs good company
Hope you can help me with this last questions
thanks

Get the cheapest one you can find. Actually, get 2 of them. All they are is a wire which is cut to the right wavelength, and they have a ball shaped ground plane towards the bottom. If you get one from a router, it will even have an IPX connector on the end of it already. I say get 2 because if you are careful, you can cut the outer rubber/plastic away and have just the wire, which will easily fit inside the gtab case, and still work even if you curl it around. They are really cheap, so if you get 2, you can mess up on 1, and still have the other.

like the image above?
and will work the same?
If it does will work the same, then i can buy a higher DBI antenna, and just curve it as an L in the angle of the Gtablet
i saw 17dbi antenna that are 20-30cm something lenght
so i can curve in the angle, and will fit great inside tablet
i'm right?

yes, you're right. If it is the right wavelength it will work, as long as it will fit. a 17dbi would be longer than that though, sounds like a FAKE. ALFA makes one that is 9dbi, thats the best REAL one I have seen.

This is not a cheapo chinese, be careful taking the plastic off. I own one of these, it works great, look at all that have been sold already.

its just that a better antenna will be 10$+ and actually i dont want to spend that money just for an antenna

[MOD/SOLDERING] Boot Kindle Fire HD 7" Into Fastboot with out Fastboot USB Cable

As I search for an alternate point to actually solder to this is the best I've got so far.
In order to completed this you must have a moderate amount of soldering experience and a damn steady hand.
EASY: First solder to the easy spot which is 3-4volts when unit is off.
Use a strand of copper from a speaker wire since the gauge is thin enough you should be able to attach it rather easily

}
HARD: Next what you want to do is hold the Kindle on an angle where you can access the power button and touch the other end of the copper wire to the following point. If the unit doesn't automatically turn on you may have to manually power it on carefully while touching the point.
HARDER: Solder to the point and run a switch in line for a fastboot/unbrick mod. Maybe later...

Great tut, however it seems there is much more work than to just make a fastboot cable.
sent fro my rooted kindle fire hd 7 with twerp and kinology rom installed

I didn't want to drop 9 bucks on eBay and after like 5 USB cable disassemblies I just said screw it and whooped out the iPod Pryer and multimeter

I have another demo unit. I'll check it out for you. But I'm pretty sure the RX TX pads shown in the picture below are what your looking for.. As for VCC you can use the 3-4v wire shown in picture 1 and ground obviously the black wire where the battery connects a few wires over from the red one.
Also I'm going to do a tutorial on how to flip a demo unit into a full blown unit/cm10 soon since that was what I was doing/did to this unit. I'll be using your files and another users files do you have any objections?

Hey! Great find. Maybe I'll open mine up tonight and run some tests.
Thanks!
No objections either.

Its not fun until you break it open to see how it works and make it better hardware wise. I can easily doing an inductive charging mod to this. Actually going to very soon since I'm selling my Sero 7 and keeping this smaller tablet.

There used to be a person here who had the signature "if it ain't broke, fix it"
Seems fitting for the two mods

I'm a hardcore hardware modder. I love tearing stuff apart. If you look in my sig the inductive charger thats in the Sero 7 after it sells on ebay its coming out and going in the Kindle HD

why not just make a option in the roms?

It's easy enough to do from terminal, this is more of the oh crap I bricked it instance, I do agree, this mod is harsh, butttttt if you were wanting to crack it open anyway.....

This is mainly for modifying the demo units sold on eBay for 1/2 the cost of normal KFires. I got a demo unit off ebay for 80 shipped and flipped it for $150 fully modded with android. I then picked up another demo unit for 70 shipped and am using it for my wife. Never spent a dime on a fastboot cable which is needed for a demo flip.

err, why wouldn't you just unplug the battery?
30 awg kynar wirerap wire and copious application of kapton tape barriers is the way to bridge traces, imo.
I wonder if there's a place on the Vcc rail on the output side to pull power from. it'd be better because the current way is skipping the power filtering/protection circuits for the battery and dumping straight pack potential into sensitive chip leads.
also, i'm guessing TX/RX is the uart?

Has this been tested on a bricked model? or was it only used on demo units?
Would like to know, since I bricked my KFHD7 and am currently waiting on a Fastboot cable that wont be here till, the 27th.
Just want to make sure before I crack mine open, will report if it hasn't already been reported to work on a bricked unit

If you have the means to do this mod and have a spare cable. I'd go with modding a cable and recommend heat-shrink over tape(improper taping is poor strain relief). He did this mod because you can't exchange a demo unit and problems making a cable.
