Dual-Circularly-Polarized High-Gain Transmitarray Antennas at Ka-Band

Abstract : This paper describes the performance of dual circularly-polarized transmitarray antennas at Ka-band with independent radiation characteristics. The proposed antenna architecture consists of a dual linearly polarized (dual LP) TA panel based on the interleaving technique combined to an add-on broadband polarizer, in order to generate independent RHCP and LHCP beams. This offers both dual-LP and dual-CP operation depending on the topology of the polarizer. The LP unit-cell are designed to achieve a 3-bit phase resolution, and the dual-LP TA panel is made of two interleaved single LP sub-arrays with 52-by-52 and 53-by-53 elements operating in 45° and 135° single linear polarization, respectively. The polarizer transforms the dual-LP into dual-CP while keeping radiation independence of each polarization across Ka-band. The experimental results obtained with three different prototypes pointing up to 50° validate the proposed concepts.
