Abstract
A single layer single element rectangular microstrip antenna on ridge ground plane for improved bandwidth is theoretically investigated with a view to develop a concrete physical insight in to the phenomenon. The simple single element probe fed rectangular microstrip antenna fabricated on conventional PTFE (Poly Tetra Fluride Ethelene) substrate have many advantages except its narrow bandwidth. The present study proposes the technique to control the resonant modes of a microstrip antenna for yielding better bandwidth using transverse resonance method. The present antenna is designed to fabricate on ridge ground plane which has been compared with conventional structure and around 6% - 7% improvement in bandwidth is revealed. The detailed variation of radiation pattern across its frequency band has been studied and presented in this paper. The proposed idea has been verified through a commercial software package (High Frequency Structure Simulator) for a patch operating in X band and explained quantitatively. The electric surface current distribution over the patch surface for both the conventional and proposed antenna is presented to explain the broad banding effect physically.

Summary
A microstrip antenna is the most useful low profile antenna due to its light weight, small size and low cost. In order to cope up with present demand different techniques have been incorporated in the rectangular microstrip patch to improve the band width These include the use of thick air filled substrates, employing parasitic elements in co-planar [2] or stacked configuration [3]. The general concept in these broadband slot cut microstrip antenna is that when these slot length equals either half wavelength or quarter wavelength it introduces modes near the fundamental mode resonant frequency of the patch which may be attributed for broader bandwidth In these techniques no concrete mathematical reasoning is provided in the literature. Rectangular Microstrip Antenna on Ridge Ground Plane to Control the Resonant Modes for Improved Bandwidth using Transverse Resonance Method firms the broad banding phenomena in the proposed structure compared to conventional one.
