Design and analysis of gain for rectangular microstrip patch antenna using symmetrical cuts

The low gain of microstrip antenna is one of the important features that that restrict its wide usage. This paper presents Bandwidth radiated microstrip patch with enhanced gain has been designed with centre frequency of 2GHz. In order to achieve gain enhancement a rectangular cut structure have been introduced in the rectangular patch antenna. Gain enhancement of 10dB at 2GHz is achieved. It is just because of Return loss is increasing in negative side as it goes from (-24dB) to (-34dB).
