Design of the Wideband Folded Transmitarray Antenna

Abstract

In this paper, a novel folded transmitarray antenna based on the polarization grid (PG) is presented. The transmitarray antenna consists of a planar transmission array, a wideband polarization rotation reflection surface (PRRS) and a wideband stacked microstrip patch array as the primary source. First, a simple three-layer double-ring transmitarray element with the PG is designed, which can reflect one linearly polarized (LP) wave while transmit its orthogonal LP wave. Then, a
