SIW H-Spaced Head slot antenna for WLAN/GIFI Applications

In this paper, Proposes SIW slot antenna for 57-64 GHz frequency with resonant frequency of 60GHz and shape of slot is used for this design is H-Spaced Head. This frequency is used for WLAN/GIFI applications. This antenna is designed by using rogers substrate material with ε_r = 2.2 and substrate height is 0.381 mm. The microstrip feed is used for this design with an input impedance of 50ohms. The structure provides 3.96GHz impedance bandwidth in between 57-64 GHz band and this band is perfectly matched with VSWR 2:1. The values of the Reflection coefficient, VSWR, Gain, transmission and radiation efficiency of proposed antenna at 60GHz are -30.862dB, 1.05, 7.2dBi, 92.35% and 82.5%.
