Design and parametric analysis of microstrip antenna array for increased gain

This paper demonstrates simple, low cost and high gain microstrip array antennas with suitable feeding techniques and dielectric substrate for applications in GHz frequency range. The optimum design parameters of the antenna are selected to achieve the compact dimensions as well as the best possible characteristics such as high radiation efficiency, high gain, etc. In this paper different microstrip array antennas such as 1×1, 1×2 and 2×2 are designed, simulated, analyzed and compared regarding to the antenna performances. The optimum feeding system is decided based on the various antenna parameters that are simulated. The simulation has been performed by using HFSS simulator which is a commercially available antenna simulator. The designed antennas provide the frequency range of 5.3143 to 5.6291 GHz by using FR4 dielectric substrate with permittivity, ε_r= 4.4 and height, h =1.588 mm. These antennas are suitable for Wi-Fi applications.
