28 GHz Switched Beam Vivaldi Antenna System for V2V Communication in 5G Applications

Abstract

A 28 GHz switched beam Vivaldi antenna system consisting of 4 Vivaldi antennas for V2V communication is presented. The proposed design is realized on a substrate material of “Rogers 5880” with εr = 2.2, tanδ = 0.002 and 0.508 mm substrate thickness. The antenna is designed to operate at a center frequency of 28 GHz with operating bandwidth of 1.463 GHz (5.23%). An overall realized gain of 9.78 dBi is achieved at the intended center frequency. The proposed antenna is designed and simulated. It is also fabricated using photolithography techniques and measured using R&S vector network analyzer. Good agreement is obtained between both simulated and measured results.
