Parameter Study of a 5G Array Antenna at 28GHz

Abstract

In this paper a 5G compact antenna has been simulated, fabricated and measured which works at 28GHz. The antenna structure is according to quasi Yagi antenna. The SIW technology has been used to feed the antenna. The antenna array has been designed and simulated. The S11, E pattern, and H pattern have been simulated for single element and array antenna too. The E pattern, H pattern, and S11 have been measured for single antenna. Moreover the effects of some antenna parameters i.e. (the number of stubs, the length of director, the distance between director and driver, the length of driver, and the distance between driver and reflector) on S11 has been studied. The HFSS and CST software have been used to all simulation. Also for the array antenna the effect of changing the number of directors on S11 and antenna gain are considered.
