Different Coupling of Notch Loaded Rectangular Microstrip Patch Antenna for Wireless Communication System

Abstract: In this paper comparisonof different shapes of coupling of microstrip patch antenna is discussed.The bandwidth of proposed design antenna is 37.43 % (2.705 GHz-1.852GHz). The antenna has been designed for 2.45GHz operating frequency and the result of different coupling is compared byIE3D simulationtool. The return loss is -15.698dB, gain of 3.7447 dBi and Directivity of6.8002 dBi. The resonant frequency is 2.5470GHz which is near to our operating frequency. The antenna is fed by 50?Micro strip line feed.
