Abstract

A 6×6 array of four-arm spiral antennas is presented for satellite receiver applications at 18 GHz. The array provides a wide-angle elevation scanning with a high gain right handed circularly polarized (RHCP) radiation beam. Each spiral element has four spiral arms with four feeding ports. The four...
