Millimeter-Wave Single-Layer Dual-Frequency Reflectarray Antenna

摘要

To fulfill the dual-frequency requirements, elements are needed to resonate at two different, independently adjustably frequencies. A low weight, low cost, and easy to fabricate single-layer dual-frequency reflectarray is designed, fabricated, and measured, with gain values of 27 and 29.2 dBi at 20 and 30GHz, respectively.
