 On the top cover you can see a metalized coating on the plastic in the form of conductive tracks and contact pads, these are Wi-Fi, Bluetooth, and GPS antennas. 

When reassembling, be sure to check that the spring contacts on the board and the contact pads on the cover match and touch, otherwise the signal may be lost or the signal may be very weak.
