Abstract
A slot antenna loaded with 2D UC-PBG pattern as the back reflector is demonstrated. The cavity height of this slot antenna with UC-PBG lattice is 16 times thinner than that of a regular /spl lambda//4 wavelength cavity slot antenna. The radiation patterns of this antenna show well defined unidirectional characteristics, and its gain is 1 dB higher than that of a conventional slot antenna at 5.28 GHz.
