Antenna

Antenna overview

The main antenna has one antenna element (GSM and WCDMA).
In the GSM/WCDMA antenna there is one feed and one ground contact.
The BT/WLAN antenna is a discreet component on PWB. The GPS antenna is also a discrete component on
PWB.

Main antenna functionality

The main GSM+WCDMA antenna is functioning normally when the feed and GND C-clips take proper contact
to the PWB, and the antenna foil is visually intact in the antenna frame. The main antenna functionality must
also be checked by measuring the transmitted power with RF coupler at GSM900 channel 124.
