ABSTRACT
This paper presents a rigorous comparative study of the effect of the geometry on ground plane on radiation characteristics of an annular ring slot antenna and found that there is great improvement by introducing the structure on ground plane .In this paper a U-shaped ground plane geometry [1] is considered. Simulation results show a variation in resonance frequency from 2.184 GHz to 1.688 GHz and a meaningful increase in bandwidth from 2MHz to 59 MHz. The simulations are carried out using Zeland IE3D software .
