Abstract:
1. An antenna assembly comprising: an antenna housing; an antenna located within the housing; a radio frequency module located within the housing and including a radio frequency device selected from the group of transmitters, receivers and transceivers electrically connected to the antenna; at least one electrical conductor operably associated with the module for conducting processed signals between the module and external circuitry without significant signal loss; a mounting base connected to the housing for connecting the antenna assembly to an enclosure, the at least one electrical conductor extending through the mounting base; a conductive sleeve located in the housing and surrounding the radio frequency module, the conductive sleeve being electrically connected to the module to thereby provide a ground plane for the antenna and a shield against outside emissions; and a spacer located between the housing and the mounting base for providing a radio frequency energy choke effect.
