Abstract
The present invention provides a radio communication apparatus for use with a host system. The host system includes an electromagnetic body which acts as a ground plane or counterpoise for the radio communication apparatus. The apparatus comprises an electronics system coupled to the host system, a radio module including a radio electromagnetic body and optionally a radio electronics system, a signal pathway operatively coupling the electronics system with the radio module, and a conductive enclosure. The conductive enclosure provides electromagnetic isolation of the signal pathway. The conductive enclosure is further configured, by inclusion of a wave trap, to impede electromagnetic coupling between the radio electromagnetic body and the host electromagnetic body via the conductive enclosure.
