Modulated Geodesic Switched Beam Lens Antennas for 5G mmWave Communication

Abstract

This paper presents design considerations for a pair of modulated geodesic lens antenna profiles along with their folding configurations for wideband 5G switched beam applications. Triple folded and double folded Geodesic curve profiles are implemented on a fully metallic switched beam antennas operating at 28 GHz for 5G mmWave applications. Double folded lens profile antenna exhibits a bandwidth of 32% and Triple folded lens profile antenna shows 21% bandwidth. Wide scan performance upto ±70° with a maximum scan loss of 1dB is achieved for both the configurations. Double folded lens antenna has a peak gain of 22.75 dBi where as Triple folded lens antenna has a peak gain of 24.5 dBi at 28GHz.
