Abstract
A planar multi-layer assembly method fabricates a dual frequency, dual polarization phased-array antenna. A plurality of vias make up an array of double-walled wells which are connected to a ground plane. A shorted annular ring patch antenna (SARPA) is deposited at the top of each double-walled well. Fabricated coaxially and parallel to each SARPA, is an array of circular patch antennas (CPA). The inner wall of each double-walled well improves isolation of the CPA signals from the SARPA signals. Each SARPA of the array is connected to a pair of first frequency band signal vias and the CPA is coupled to a pair of second frequency band signal vias. Within each frequency band, a plurality of signal phases enable steerable polarized antenna beams.
