چکیده
This paper presents the design and implementation of a square patch antenna using finite element method. A balanced square patch antenna model has been constructed using FEM (Finite Element Method) with COMSOL multiphysics environment. A parametric analysis is carried out to analzse the performance of the proposed antenna on the basis of Antenna impedance, Radiation frequency and Radiation pattern. The proposed antenna is made for 6 GHz frequency. From the simulation results it is found that very good radiation lobes with negligible side lobes are obtained. The optimum values of power density and impedance of the antenna are also obtained at optimum frequency 6.18 GHz.
