A Ku-Band Magnified Active Tx/Rx Multibeam Antenna Based on a Discrete Constrained Lens

This paper presents the design, manufacturing, and testing of a Ku-band magnified active Tx/Rx multibeam antenna based on a discrete constrained lens. Multibeam antennas based on constrained lenses generate a significant number of beams on a large operative frequency bandwidth. The main novelty and...
