A Dual-Plane Beam-Sweeping Millimeter-Wave Antenna Using Reconfigurable Frequency Selective Surfaces

In this letter, a dual-plane beam-sweeping dielectric resonator antenna (DRA) using cantilever enabled frequency selective surfaces (FSSs) is presented. The proposed antenna consists of a conventional cylindrical DRA and a hexagonally arranged active FSS operating at 30 GHz frequency band. Initially...

Description
Summary:In this letter, a dual-plane beam-sweeping dielectric resonator antenna (DRA) using cantilever enabled frequency selective surfaces (FSSs) is presented. The proposed antenna consists of a conventional cylindrical DRA and a hexagonally arranged active FSS operating at 30 GHz frequency band. Initially, the reconfigurable FSS using cantilever beams is designed and analyzed. Furthermore, a prototype of the proposed antenna with FSS is designed, fabricated, and measured. The beam sweeping is obtained in both azimuth and elevation planes of the antenna. The whole azimuth plane is covered by the switched beams in six steps of an angle of 60 ^\circ. In the elevation plane, two steps of angles are obtained at 90 ^\circ and 30 ^\circ. The measured antenna gain of 8.1 dB is obtained.
