Abstract: The microstrip antenna is used widely because of their numerous of advantages, newlinesuch as its small volume, low weight, electrically thin, conformal and ease of newlinefabrication with printed circuit makes it a demanding candidate for several applications. newlineDue to increasing requirements for wireless system, the demand for smaller as well as newlinelow profile MSA increases. The increasing demand calls for the further development of newlinethem. The microstrip antenna radiate because of fringing fields between ground and newlineperiphery of the patch. The main drawback of microstrip antenna is its narrow newlinebandwidth and low gain. To overcome the drawbacks of antenna several methods has newlinebeen proposed by different researchers. The impedance bandwidth of microstrip antenna newlineis dependent on dielectric substrate constant and dielectric substrate material height. As newlineincreases the height of the dielectric substrate material, the impedance bandwidth newlineincreases. This research work is to design a miniaturized size, wideband microstrip newlinepatch antenna for different wireless applications. Basically the gap coupling newlinemethodology is used to obtain the desired results of wide impedance bandwidth. newlineThe improvement in impedance bandwidth (S11) of microstrip antenna is newlineenhanced by gap coupling method without changing overall dimensions of the antenna newlinestructure and performance of the antenna is also observed by varying the gap between newlineparasitic patches and dimension of feed width strip. The bandwidth of gap coupled newlineantenna depends on gap between parasitic elements, as increases the gap, the bandwidth newlineis also increased up to a certain level and wideband result is obtained. After certain newlinevalue of gap, the bandwidth is decreased due to increases of spurious radiation and newlinecharacteristic changes wideband to dual band and bandwidth decreases. newlineIn addition, the circuit concept method is used for the theoretical analysis of the newlineantenna and compared the simulation, theoretical results with measured results. The newlineperformance of other parameters of the proposed antenna is also evalu
