As well as the internal photos advised by Tom, also use the SAR report
and
plots which show the points of radiation and relative strengths. However, it
still doesn’t give you the actual radiation pattern though. What you really
could do with is the North American CTIA OTA (Over The Air) test results. I
doubt these are in the public domain.
Apple has a "Works With iPhone" certification programme for iPhone
accessories which includes OTA tests. Theoretically if you purchase a
certified product it should work to Apple’s defined standards (chortle).
There’s been quite a lot of discussion about the RF sensitivity of the
iPhone, Google ‘iPhone antenna sensitivity’ for more information.
Considering the broad antenna performance requirements, design constraints and
compromises that have to be made to achieve acceptable performance across the
board, I’m amazed these things ever work at all!

Subject: [PSES] iPhone Radiation Pattern
Date: Tue, 1 Sep 2009 23:13:11 -0700
Can anyone tell me where I can find out the antenna location,
orientation, and radiation pattern for an iPhone? Thinking about
docking things and why one dock interferes with phone
communications and why another does not interfere. First look
suggests something getting in the way of the antenna pattern.
Thus the question - where is the antenna and what direction is the
radiation pattern? And if one version phone is different from
another, please tell me as man as you can.
Thanks in advance for your help.
Regards,
Scott Douglas
