Re: Antennae?
If headphones plugged into the 3.5mm are used for the antenna, I wonder if it would even work for headphones plugged into a Lightning or USB-C port? If you're using wireless headphones, forget it.
At the top of the FM band, 108 MHz, the wavelength is 2.77 meters. So even if you were willing to include an antenna over an inch long - wasting precious internal space for a feature few will ever use - you're talking about an antenna that's only 1/100th of the wavelength!
An antenna at such a tiny fraction of the wavelength is incredibly inefficient, you'd need to be very near the broadcast to pick anything up. I guess you pretty much have to use the headphones as an antenna, but that's another reason why hardly anyone uses FM on their phone....though the biggest is that commercial radio is so full of ads it is impossible to listen to. Even free ad supported streaming radio like Spotify has far fewer ads - and at least there you have a lot more choice about what you're listening to.
