Abstract
The invention is a passive parabolic antenna system for use with conventional subscriber module radio antennas. The passive parabolic antenna system includes a microwave feed assembly that forms a resonant cavity coupling device for coupling to an internal patch antenna of a conventional subscriber module radio antenna. A method of boosting signal strength of a conventional subscriber module radio antenna and a wireless communication system are also disclosed.
