Abstract :
The effect of using a superstrate PBG material on a microstrip line fed slot antenna is investigated. The PBG material is composed of periodic metallic blocks inside a host dielectric material with high material permittivity, and exhibits a complete bandgap at the design frequency of the slot antenna. Simulation results show that by adding the PBG layer as a superstrate, radiation in the E-plane near the endfire direction is suppressed, while radiation in the H-plane is enhanced.
