Compact Multi-beam Antennas for Full-azimuth and Hemispherical Scan Coverage

Abstract

This paper presents the results of numerical electrodynamic simulation of multi-beam antenna systems for full-azimuth and hemispherical scan coverage operating in the frequency range of 27–29GHz. Both antennas can be manufactured using multilayer PCB technology. Antenna system for full-azimuth scan coverage can form 16 beams with directivity about 10–11dBi. The hemispherical antenna has a minimum gain in azimuthal plane of 4dBi and a maximum gain of about 9.5dBi. The polarization of this antenna can be arbitrary and is determined by the type of feeds of the metamaterial lens.
