Abstract
The concept of generating two spaced beams in dual-CP by variable rotation technique (VRT) is validated for the first time by manufacturing and measuring. A reflectarray demonstrator has been designed, manufactured, and tested to deviate ±10° the beam of a dual-CP multiflared horn at 19.7 GHz. The proposed reflectarray cell for VRT is made of a conductive cross printed on a grounded dielectric. The experimental results show that two adjacent beams in dual-CP maintain the correct directions in the prescribed frequency band (19.2–20.2 GHz). The results are satisfactory and validate the concept for generating two spaced beams in orthogonal CP by VRT with a single feed.
