Abstract

In this paper, an idea of radiation pattern modification using symmetrical slots in an elliptical microstrip patch antenna partially loaded with mue-negative (MNG) metamaterial has been proposed. Previously, size reduction of conventional elliptical microstrip patch antenna has been possible by using MNG metamaterial. But the idea of using symmetrical slots to modify higher modes in such metamaterial loaded elliptical patch antenna is different and a novel concept. Using this idea novel design of slot loaded elliptical microstrip patch antenna partially loaded with MNG metamaterial has been introduced successfully. In this paper, slot loaded elliptical patch antenna partially loaded with MNG metamaterial is theoretically and numerically analyzed. Actually, this mode modification has been done by MNG metamaterial & newly introduced symmetrical arc shaped slots with the help of proposed better radiation conditions, relevant theory of dispersive metamaterial and realistic simulated results. The potential application of this novel idea is the way to design multiband antennas using appropriate metamaterials (ENG or MNG) and using the idea of additional modified modes in elliptical patches also.
