Abstract :
A high-gain aperture coupled antenna with superstrate structure for 60 GHz communication is proposed. Unprinted dielectric slab acts as superstrate is added above the antenna in order to increase the gain performance. Then, the effective radiated area and transmission line model are used to further enhance the gain. The maximum simulated gain of the antenna with superstrate structure can achieve 15.2 dBi at 60 GHz and is more than 13 dBi all over the 60 GHz band (from 57 to 66 GHz). From simulated results, the radiation patterns are found to be broadside all over the frequency band.
