DCFirst Claim
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.

Abstract
An antenna assembly includes an antenna housing, an antenna located within the housing, a radio frequency (RF) module located within the housing and connected to the antenna, and a wire assembly operably associated with the module. The module includes a radio frequency device, such as a transmitter, receiver or transceiver, electrically connected to the antenna. The wire assembly includes electrical wires for providing external power to the module and conducting processed signals between the module and external circuitry. The proximal nature of the antenna and RF module reduces or eliminates induced power losses between the antenna and module, resulting in a very effective power transfer ratio. A conductive sleeve is located in the housing and surrounds the RF module. The conductive sleeve is electrically connected to the module to thereby provide a ground plane for the antenna and a shield against outside emissions. A spacer located between the sleeve and the mounting base together with a step between the sleeve and the wire assembly provide a choke effect for the RF energy.
