Have you ever wonder why your iPhone 6 lineups have horizontal lines at the back? If you look at the back of your new iPhone 4" or 5.5", you will actually see the white lines on top and the bottom your your iPhone's back. 

It's because that's where the phone's antenna locates. Unless Apple didn't locate that space with plastic, radio waves could never be able to get through your iPhone exterior to receive and send signals.

These antenna can't be hidden inside the handset, because the phone's metal would prevent the go-out of the radio connectivity by preventing the antennas from sending and receiving information. 

This is the reason why Apple decided to place the antenna in the white plastic lines through which the radio wave is able to pass.
