Antenna location, where exactly is it?

[iunlock]

Is it on the cover? On the phone body itself?

Anyone know the exact location of where it's located?

Top and Bottom of the back cover

Thanks...I'm assuming that the main antenna is toward the bottom of the phone since people have been complaining about the death grip issue?

If the main antenna was indeed on the very top then the death grip would be irrelevant since the top never gets covered by your hand. When holding the phone, the hand usually grips the middle-bottom portion of the phone.

Pretty interesting....hhmm..

I take it the very upper left gold contact part and the bottom gold part are where the antennas are located? ?

Top and Bottom of the back cover

 

[heygrl]

All of them are antenna contacts. Two for the cellular radio (one at the top and one at the bottom), one for the GPS and one for the BT/WiFi

Not true. It's touching or covering the top area of the phone that causes the wifi problem. It typically occurs in landscape mode where the left hand is holding the top back part of the phone. You can see vids on YouTube showing it. It's also been shown just by touching the very top edge, or specific spots on the top side of the back.

I was referring to specifically to the cell phone signal. As mentioned, I have reason to believe that the bottom antenna may be the main voice/web (3g/4g) signal? Which may be responsible for the death grip?

Anyhow, I just wanted clarification as to what the four gold points are specifically responsible for.

So let's start with the bottom. That may be the voice/web antenna?

Upper right (two gold contacts) wifi and gps?

Upper left (one gold point) for voice?

Death grip people are talking about is wifi, not mobile network. I don't have problems with mobile network signal, but I have BIG problems with wifi.

Top plastic (where the camera is): wifi & BT antenna
Bottom plastic: mobile network antenna

Oh, and there is another contact on T-Mobile version (top left) but I'm not sure what it's for.

The top contact is for the additional antenna that gives the HTC Sensation 4G receive diversity AKA less of a death grip effect when using the phone in portrait mode. It's an additional antenna

OK, help me fill this in, as I cannot find the info anywhere.

A = ???
B = WiFi
C = GPS - also, under plastic is MMCX external antenna connector
D = ???
E = ???

Answers:
GPS
WiFi
GSM
3G/4G


EDIT (10/30/2011): Thanks to member dirtyblueshirt

A is the GPS antenna.
B is the WiFi/Bluetooth antenna. (I agree, tested pins)
C is the "Diversity" antenna (rx only). (Can't be, I just tested and got GPS signal to be stronger on these pins)
D/E is the GSM/WCDMA antenna.

Actually A is the RX diversity antenna, and I'm pretty sure the WiFi and BT antenna is the one below the camera opening. Not sure though

The main cellular antenna is definitely at the bottom.

A is GPS and Diversity is below the camera per the FCC filing attached here:

My current theory (since the XE lacks antenna "A") is that if the filing photo is correct, the Diversity antenna may act a backup for the GPS antenna. Or the filing could be wrong and GPS/diversity are switched, in which case the XE doesn't have a Diversity antenna.

That's what I was thinking, the international Sensation doesn't have the contact there (A) and the Sensation 4G is the one with RX Diversity. It wouldn't make a whole lot of sense for them to completely switch the antenna spots around. It could be possible tho

This is the back of a UK Vodafone sensation, i.e. minus the 4G.

Sorry for the ****e quality, I didn't realise it was so bad until I's transferred it to the PC.

Do u got any solution for the wifi and bluetooth problem ???

which problem? I found the extra connector of the 4g series. it's hidden behind a stock plastic, that could be easily removed after opening the shelf of the phone.

I have the HTC Sensation 4G (z710a from Bell) and it does not have the A-pin.
Nonetheless all connections (BT, Wi-Fi, GPS, mobile network) are working great!

As seen on the picture, the mentioned A-pin is missing on both covers. The left one is what I have for daily use and the right one came with my phone.
I have a second white cover and the pin is missing, too.
