Abstract
An apparatus for sensing the integrity of an antenna which is located within a wristband and which is coupled to a wrist worn communication device having a receiver, and an antenna sensing circuit which generates an antenna sensing signal. The antenna sensing circuit monitors the antenna sensing signal and derives an antenna integrity indication signal which indicates the integrity of the antenna. An indicating circuit is responsive to the antenna integrity indication signal and provides a sensible indication of the integrity of the antenna, such as a message indicating the antenna is open.
