Triple Band Microstrip Patch Antenna with L Shaped Slots on Ground Plane

Abstract

Conventional Microstrip Patch Antennas have a PEC ground plane and because of this reason its bandwidth is always narrow.  In this paper, a novel triple band antenna model is presented in which L shaped  patterns are etched on  its ground plane making it a magnetic plane, resulting in  superior radiating features due to effective elimination of surface waves (because of slots in its ground plane). The proposed antenna resonates at three frequencies, i.e., 2.36, 3.42, 4.46 GHz.  This antenna has an adequate gain of 4.6, 4.5, 3.3 dBs respectively at its resonances, exhibiting linear Polarization.
