Circularly-polarized reconfigurable transmitarray in Ka-band

Abstract : In this contribution, we present the design of a 400-element electronically reconfigurable transmitarray working in Ka-band with 180° phase-shifting unit-cells. The sequential rotation technique is applied to generate a circularly-polarized beam over a broad frequency band. The proposed configuration exhibits a broadside gain of 20.3 dBi at 29.0GHz and cross polarization discrimination of 30.0 dB. Multiple focal sources are also used to reduce the overall antenna thickness. © 2016 European Association of Antennas and Propagation.
