Antennas are fundamental component of wireless communication devices as such, there is an increased need for small, conformal, lightweight and efficient antennas to suit this wireless application. Antennas for Wifi applications can be embedded on the body of an equipment or a device. The characteristics of these antennas are unlike that of the conventional Aperture, linear and array antennas, which are though bulky and efficient but cannot be used for portable wireless devices. In this work therefore, the design requirement and simulation of a microstrip (patch) antenna for Wi-Fi application was carried out. The work investigates the parametric variations of a rectangular microstrip antenna in other to ascertain the implications of these variations in achieving the desired antenna performance. The method of solution was achieved with the use of CST software. It was shown in this work that; 1. Antennas which possesses less VSWR is expected to have a good return loss. 2. A slight change in patch dimension brings about a significant change in the resonance frequency and subsequent increase in the bandwidth of the antenna.  The designed antenna will find application in short range wireless communication devices operating at frequency of 2.4GHz with return loss less than -10dB and producing a gain above 5dB.
