Quote from Roger Podacter:
Can anyone tell me exactly where the GSM/3G HSDPA antenna is located in this teardown? I know the cellular antenna on the nexus is located in the bottom of the phone. but where EXACTLY is it on these pics? its not totally clear or labelled anywhere. Thanks.
Look carefully at Step 7, second picture. The piece in the technician's hand contains the antenna. It is a black, flat metal piece riveted to that small module, with white writing on it. A similar style of antenna is used in the T-Mobile G1. The little round connector is an antenna connector. If I had to guess, there's probably a connector on the underside of that module to connect it to the antenna connector on the board.
Quote from Inino:
If the antennas are on the bottom, the reception would be reduced everytime the phone is grabbed.
Just like the iPhone, when you grab it the hand reduces the reception thus the iPhone has bad reception.
The human body doesn't attenuate reception much at the frequencies used by mobile phones. By placing the antennas at the bottom, it reduces interference with hearing aids, because the antennas are farther away from the electronics in the hearing aid.
There may be other reasons, but those are the ones I know of.
