LHCP/RHCP Reconfigurable Transmitarray in Ka-Band

Abstract : In this contribution, we propose the design of a circularly-polarized reconfigurable transmitarray based on a 1-bit unit-cell (i.e. with two phase states, 0 degrees and 180 degrees) operating in linear polarization. Applying the sequential rotation technique, the possibility to switch between the two circular (LHCP/RHCP) polarizations will be presented. The numerical results obtained for a 400-element transmitarray radiating at broadside show a maximum gain of 20.3 dBi at 29 GHz with a cross polarization discrimination better than 30 dB. The -3dB bandwidth in gain reaches 14%
