A Millimeter-wave Fabry Perot Cavity Antenna with Reconfigurable Beams

Abstract

In this paper, a wideband millimeter-wave Fabry-Perot Cavity (FPC) antenna with high gain and switched beams is proposed. The antenna operates at millimeter-wave band and it achieves three reconfigurable beams at -18°, 00 and 18° with respect to broadside radiation direction. At the same time, the realized gains of the three radiation beams are all above 16 dBi. Compared with recently reported designs, the proposed antenna acquires advantages of high gain, low cost and large beam tilting angles. The above-mentioned characteristics ensure the proposed design become a potential candidate for millimeter-wave communications and 5G applications.
