This patch antenna is integrated with a cavity resonator. The antenna acts as both part of the cavity filter and as a radiating element for the cavity filter / antenna system. The design of the antenna was rigorously synthesized to ensure that the integrated filter/antenna has all the analogues of an equivalent three-pole filter in terms of resonators, internal couplings, and external couplings. Due to the high Q factor (~700) of the cavity resonator and near loss-less transition between the antenna and filter, the overall efficiency of the filter/antenna system approaches 91%. This new filter/antenna architecture enables compact and low-loss RF front ends and phased array systems.
