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.

Abstract: A radio frequency connector for a patch-coupled aperture array antenna is described including a coaxial connector having an outer shield and an inner conductive member with a dielectric material disposed between the outer shield and a portion of the inner conductive member and a dielectric substrate having a first and a second surface with an opening extending from the first surface of the dielectric substrate to the second surface of the dielectric substrate, the inner conductive member extending through at least a portion of the opening of the dielectric substrate. The radio frequency connector further includes a coupling conductive members having a protruding pin, the protruding pin connected to the inner conductive member and a sheet of dielectric material disposed juxtapositional with the dielectric substrate and covering the coupling conductive member. With such an arrangement, a less expensive radio frequency connector for an antenna is provided which can survive a high temperature environment.
