Millimeter-wave Dual-plane Beam-switching Antenna based on Cantilever enabled FSS

In this paper, a beam-switching dielectric resonator antenna (DRA) using a cantilever enabled frequency selective surface (FSS) at 30 GHz is presented. The frequency reconfigurability of the FSS is used for switching the beam in both azimuth and elevation planes. Six panels of a lx6 array of proposed FSS are arranged in a hexagonal configuration around the DRA to obtain the beam switching. The simulation results show beam switching covering the whole azimuth plane in six steps along with two angles in the elevation plane.
