Compact Dual-Circularly Polarized Reflectarray Antenna Using Semicircle Strips Elements With Independent Focus and Beam Directions

This article introduces a compact dual circularly polarized (DCP) reflectarray antenna (RA) with independent focus and beam directions for satellite communication. The reflectarray employs semicircle strip elements with slots on their diameters, which facilitates adjusting the opening direction and...
