Hey there

I am studying RF at University and i have an interest in the topics of antennas also. My professor does not really know how the iPhone 7 antenna actually works, so i was hoping someone here would know. Does anyone have a clear diagram of what the actual antenna topology looks like for this?

Some hints:

- iphones (all smartphones) have multiple antennas:
* GPS
* primary cellular
* diversity cellular
* WIFI/BT (1 or 2)
* NFC

Go to ifixit and look for coaxial cables. Those are sure hints of antenna feedpoints, which must connect back to the radios on the PCB.

Make sure you understand his page too:

Outside of that, you need to do it on your own
