I posted this question on the Apple support forum, but no one could give me an answer.
I am researching iBeacons for my final year project at University and I'm interested to know the position of the Bluetooth antenna in the iPhones.
Can anybody give me a reliable source explaining where the bluetooth antenna is located on the different versions of the iPhones? iPhone 4S up to 6 plus.
Cheers.

There are teardown/repair guides at iFixIt, they note where the chips and antennas are located.
For example, in an iPhone 4S teardown, here's a photo of the Wi-Fi/Bluetooth chip.
There is a guide on replacing the upper antenna - which is the Wi-Fi/Bluetooth one.
And there is also a step-by-step guide on fixing the wi-fi which provides the detailed photos and description.
It appears that the Bluetooth antenna is located at the top of the 4S. The discussion of the iPhone 6 teardown also states that the Apple fit the antenna on the top.
So, iFixit has a lot of manuals and photos to provide. Also, they've got a great community, so if you have any further questions, you can ask them instead.
