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 cable 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 cable 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. Resulting processed signals between external and internal processing circuitry can be conducted over relatively long lengths without appreciable signal loss.
