Dual-Band, Beam-Steerable Reflectarray with Independent Beam Control at X- and Ku-Bands

Abstract

Reconfigurable reflectarrays (RAs) have attracted significant interest as affordable and relatively low-complexity beam scanning antennas for radar and satellite communication applications. We present a dual-band, beam-steerable RA capable of independent beam control at X and Ku bands based on a 1-bit polarization-rotating unit cell (PRUC). Two static versions of the RAs with different beam scanning scenarios are simulated, fabricated and measured. Good beam steering performance with independent beam control at each band is achieved.
