Abstract

The incorporation of number of unit cells in EBG arrangement produces two major side effects on the performance of patch antenna. First one is parasitic loading, this causes multi resonance in antenna hence obtains some enhancement in antenna band width. Second one is cavity effect, this reflects some of energy from EBG toward antenna which results in reducing bandwidth. Present paper, rectangular microstrip patch antenna is surrounded by number of EBG rows is designed; and the results of proposed antenna with a conventional patch antenna is presented comparatively.
