INTEGRATED CAVITY FILTER/ANTENNA SYSTEM

摘要

An integrated cavity filter/antenna system includes a substrate, a cavity filter formed in or on the substrate. A first cavity resonator is in or on the substrate that is enclosed by metal walls. At least a second cavity resonator is formed in or on the substrate that is enclosed by metal walls. An inter-resonator coupling structure couples energy between the first cavity resonator and the second cavity resonator. An antenna is integrated with one of the cavity resonators so that the antenna acts as both a port of the cavity filter and as a radiating element for the filter/antenna system. A connector is coupled to one of the cavity resonators for coupling energy into the filter/antenna system.
