One of the major limitations of microstrip antenna is narrow bandwidth. Various techniques can be used to improve it’s BW. In this paper, Proximity coupling technique and X slot are employed to enhance the BW of Rectangular Microstrip antenna (RMSA). A RMSA with X slot has been designed at a frequency of 2.45GHz on FR4, one substrate and it is proximity coupled with microstrip feed, which is on the other substrate. Various parameters viz. Return loss, VSWR, input impedance, Gain, are obtained from HFSS simulation and Network analyzer test is performed to obtain VSWR. Percentage BW of VSWR from network analyzer is obtained as 7.14, which is more than that of a microstrip feed RMSA.
