BT Antenna
The BT antenna is a stamped, trimmed metal sheet formed with two spring contacts and
heat staked to a plastic support structure. This antenna is located to the right of the
battery with the baseband shield under it. It is inserted into the D-cover and makes
contact with two PWB pads below it. There is a hole in the top of the D-cover used to
catch a locking feature on the BT antenna plastic module. This outer catch and the catch
on the inside of the D-cover must be properly engaged. There are no antenna impedance
matching elements for BT on the main PWB.
