The sizes and weights of various wireless electronic systems (e.g. mobile handsets) have rapidly reduced due to development of modern integrated circuit technology. However, microstrip antenna suffers from low bandwidth. The objective of this project was to improve the bandwidth by proposing square ring technique and investigation for the enhancement strategy of bandwidth performance and analysis of different commercially available dielectric materials. The performance of different dielectric material for design of a square ring microstrip patch antenna is analyzed in terms of bandwidth. A square ring microstrip patch antenna was designed not only to improve the antenna bandwidth but also to reduce the size of the conventional microstrip patch antenna. Analysis of the design of microstrip patch antenna at C-band frequency range (4-8GHz) has been carried out using commercial available computer model of CST. This study will help for authors and researchers to get a fair idea of which substrate should be given preference and why for fabricating microstrip patch antenna. It has been shown that the use of square ring antenna produces an optimum bandwidth performance of approximately 5.9% in roger material for using fabrication. Experimental work has been performed to validate the predicted results obtained from CST analysis by using network analyzer. Both simulated and measured results have shown a good agreement.
