Planar Quasi-Yagi Antenna for Future 5G and WiGig Applications

Abstract

This paper presents a planar quasi-Yagi antenna that covers the operating bandwidths of 28 GHz, 38 GHz, and 60 GHz. Experimental results show that the fabricated antenna can achieve a 10-dB impedance bandwidth from 25.8 GHz to 29.8 GHz and from 33.2 GHz to > 67 GHz, and can demonstrate consistent end-fire patterns and peak gain greater than 6 dBi over the entire bandwidths.
