At the other end, 2 big flex cables are brought together by a small control board. Disconnect the 2 clips (Green - LCD and Orange - Digitizer) and the other ends of the antennas. Then remove the antenna wires completely.

This small control board is also held down by a little adhesive, but can be carefully pried up.

In the third picture, marked in the Green square, is a piece of plastic that is attached to the board. It is better to just pry it up with the board than disconnect it.
