Dual-band 20/30 GHz circularly polarized transmitarray for SOTM applications
Abstract : This paper presents a five-layer circularly-polarized transmitarray antenna operating at downlink (19.7-20.2 GHz) and uplink (29.5-30 GHz) Ka-bands and illuminated by a metallic circular cavity perforated on its top aperture with a crossed-slot. The proposed dual-band transmitarray design is based on a unit-cell composed of split-ring elements, providing phase-shift in transmission by their physical rotation. The initial antenna system already shows promising results in terms of directivity and axial ratio that can readily be improved using optimization methods. © 2016 European Association of Antennas and Propagation.
