ABSTRACT:
An antenna is described including strip conductor circuitry for interconnecting a plurality of patch radiator elements to a common feed. The strip conductor circuitry includes a plurality of four port quadrature couplers having an isolation port. The antenna further includes a plurality of radio frequency terminating loads and a technique for capacitively coupling one of the plurality of radio frequency terminating loads to the isolation port of a corresponding one of the plurality of four port quadrature couplers of the strip conductor circuitry. With such an arrangement, a least expensive antenna is provided which can survive a high temperature environment.
