Asymmetric Ridge Waveguide Slot Antenna Using High impedance surface
High-impedance surface (HIS) is a kind of electromagnetic bandgap (EBG) structure utilized as a ground plane for asymmetric ridge waveguide slot antenna in order to improve its radiation characteristics. As compared to a solid metal ground plane, the results suggest that a high-impedance ground plane (HIGP) can significantly improve the pattern of the slot antenna. The ripples in the Eplane pattern of the slot antenna with a metal ground plane are found to vanish, the back lobes are reduced, and the antenna gains are increased.
