Abstract: 

In this work, an aperture coupled microstrip patch antenna fed by substrate integrated waveguide (SIW) has been designed for wireless local area network (WLAN) application. The designed antenna shows an increase in gain, radiation efficiency. The overall performance of the antenna increases when fed by SIW compared with conventional aperture coupled microstrip patch antenna. The radiation efficiency increases by an approx 46%.
