Since the inception of microstrip patch antenna constant efforts are being made to modify the overall performance of this class of antenna field. Although the microstrip antenna has some of shortcoming till this date such as low gain, narrow operating bandwidth, poor radiation efficiency, yet it has been one the most suitable candidate for modern wireless communication technology. This paper focus on the bandwidth enhancement of microstrip circular patch antenna by introducing a narrow rectangular slit of length 12 mm and width 0.6 mm and thickness 0.2 mm on the conventional circular patch.
