Abstract

This paper reports an overview of recent advancements on transmitarray antennas at CEA-Leti in collaboration with IETR. Two fixed-beam and an electronicallysteerable prototypes are presented. The first fixed-beam transmitarray radiates orthogonal linear polarizations at K/Kaband. The second achieves wideband high-gain performance at 300 GHz using low-cost vialess technology. The reconfigurable transmitarray leverages on an efficient and low-power solution to attain beam steering and switchable circular polarization at Ka-band. Excellent scanning capabilities in a field of view of ±60°, with low axial ratio are experimentally demonstrated.
