Checking antenna functionality

GSM antenna

In the GSM antenna, there is one feed and two GND contacts.
Between GND1 and Feed, a DC short-circuit can be measured.
GND2 has no DC connection to the other contacts.
The antenna is functioning normally, if the contact pads hit the antenna C-clips on the PWB and the antenna
is visually intact.
BT antenna
The BT antenna is (as the GSM antenna) placed on the flex foil on the antenna module. It has one feed and
one short contact. The antenna is functioning normally, if the contact pads hit the antenna C-clips on the
PWB and the antenna is visually intact.
