Improved Gain and Bandwidth Performance of a Rectangular Microstrip Patch Antenna using Conventional Techniques in a Novel Sense

Abstract

The technique of extending the width of the patch and that of introducing slots in the patch and the groundare exploited to enhance the gain and bandwidth performance of a basic rectangular microstrip patch antenna. The used techniques, though conventional but the sense in which they are employed is unique. The rectangular patch antenna geometry considered at the primary stage has been simulated. The extension in the width of the patch to improve gain is achieved in each of the four steps. In the fifth stage, slot is introduced into the patch resulting into appearance of an additional band. The final stage witnesses an introduction of identical slots into the ground that would result into an improved bandwidth. The designsof the two final stages have been fabricated and validated. The measured results have been found to be in close agreement to the simulated results
