Dual Beam High Gain Antenna for 5th Generation Communication System using Metasurface Lens

Abstract

In this paper, a dual beam high gain compact metasurface lens antenna for 5th generation mobile communication system operating at 28 GHz using a wide band transparent metasurface is designed. First, a single layer thin highly transmissive metasurface lens with wide 3 dB transmission band of more than 10 GHz transmission bandwidth with maximum resonance at 27.5 GHz is designed. This single layer MS lens is used to achieve gain enhancement of about 5 dB in the broad side direction by placing over a microwave radiator operating at 28 GHz. A dual beam high gain antenna is designed by placing a double layer stacked same metasurface lens on the top of radiator resulting in to broad side gain of 13.5 dBi with gain enhancement of about 7 dB in the direction of ± 10° at 28 GHz.
