Abstract

The feasibility of designing single-feed transmitarray antennas with simultaneous multiple beams is investigated in this paper. Different far-field pattern masks and fitness functions are studied for multi-beam designs, and phase synthesis is achieved using the particle swarm optimization technique. A quad-layer configuration using double-square rings is selected for the transmitarray elements, and several designs of quad-beam transmitarray antenna are studied. A Ku-band symmetric quad-beam antenna with 50° elevation separation between the beams is demonstrated.
