Paper Title
Effect of Ground Plane Size on Metamaterial based Patch Antenna

Abstract
Microstrip Patch Antennas can be designed with different ground structures such as full ground plane, partial ground plane, defected ground structures (DGS), etching of split ring resonators (SRR) on ground. In this paper 5 different ground sizes are used. A CSRR unit is etched on patch to get multiband frequencies. This paper describes effect of change in size of ground on patch antenna. The simulations were carried out on CADFEKO 14.0 software. Antenna parameters (reflection coefficient, VSWR, bandwidth, impedance, gain, radiation pattern) were noted for different sizes of ground. Results were compared for choosing the best size of ground. Keywords - Microstrip Patch; SRR; FR 4; Ground Plane Size.
