Abstract

A low-profile microwave holographic antenna comprised of a dual-metasurface and an integrated printed Yagi feed is presented. The proposed design utilizes two metasurfaces with an aperture size of 0.0134 m2, with no ground plane, to produce a single pencil beam normal to the plane of the Yagi feed. The holographic antenna is designed at a centre frequency of 20 GHz and shown to have an excellent performance in the frequency range 19.75–21.25 GHz. The aperture efficiency and 1 dB gain bandwidth achieved are 28% and 7.5%, respectively. This is an improved aperture efficiency/bandwidth combination over that of comparable low-profile holographic antennas. Simulated and measured results demonstrate the advantages of the proposed design.
