Abstract
A novel beam-steerable dual-beam reflectarray antenna system is presented. It consists of hexagonal-shaped unit cells (UCs) arranged in a honeycomb lattice structure. Each UC is formed by a conductor-backed strip dipole loaded with a varactor diode for adaptively adjusting its reflection phase. To find the compensation phases for the UCs, a simple optimization algorithm is proposed and integrated with ideal reflectarray analysis. Each row of the reflectarray is considered as a linear subarray and optimized independently. In each subarray, the even and odd numbers of UCs are designated respectively for the two targeted beams, and optimized separately. For verification, some promising results acquired using the proposed algorithm and reflectarray structure are presented.
