Bandwidth enhancement for microstrip antenna as two half disk with different two radii

Abstract

Simulation of microstrip antenna as two half disk with different two radii isachieved, using MicroWave Office 2000 (MWO2000) depending on Moment Method(MoM). By considering decreasing radii exponentially with respect to the circle angle.We found an increase of the bandwidth from 6.4% up to 10.65% nearly, when we usefoam with dielectric constant
