Wideband dual-circular polarized spiral antenna phased array

Abstract : A wideband dual-polarization, low-profile cavity backed four-arm Archimedean spiral antenna is first presented. This is further extended to a linear array of spiral antennas. Beamforming capability of the linear array for both polarizations is measured and presented for a 4:1 bandwidth.
