Abstract :
A modified Plate ZAGI Antenna proposed, analyzed, and simulated in this paper. In this Antenna instead of normal reflectors we used a high impedance surface reflector, which is made of continuous metal that conducts dc current and eliminates ac current with a certain bandwidth. This new surface omits surface waves. Because of that, image currents are not phase reversed. Simulation results show considerable gain increasing in proposed antenna against usual antenna.
