Enhancement of quasi yagi antenna design for Ka-band application

A quasi-yagi antenna Ka-band frequency range has been proposed and simulated. It consists of three directors, a driver, a stripline feed, a substrate and a ground plane. Optimasion is obtained by modifying components design parameters' value. From simulation results, the designed quasi-yagi antenna has small and compact size and works well on Ka- band, mainly at 28 GHz. At 28 GHz, its return loss, gain and beamwidth are -18 dB, 8.12 dB and 57.2 degree, respectively. Based on its performance at 28 GHz, the designed antenna can be implemented for 5G application.
