H-shaped microstrip antenna for broadband communications at 60 GHz

Abstract

A low cost high-efficient microstrip line fed antenna for 60 GHz communications is presented. An investigation for microstrip antenna presently being working at lower microwave frequency has been done for 60 GHz communication. A new geometry has been presented in form of H shaped design with feeding from microstrip line. The results have been simulated using high frequency structural simulator (HFSS).There is a comparison between two antennas one with superstrate and one without superstrate is also presented. The use of superstrate has resulted in improved bandwidth and increased gain. The presented antennas are for broadband communications offering 6.3 GHz and 7.1 GHz bandwidth for one without and one with superstrate respectively.
