Square Patch Antenna: A Computer Aided Design Methodology

A novel best results micro strip patch antenna is presented. Inset line feed is also designed. Design of micro strip patch antenna in L-band at 1.897 GHz frequency is reported in this research paper. It is shown that the design adopted for microstrip patch antenna is quite accurate. The proposed antenna are designed on the substrate of dielectric constant 4.4 and thickness 1.6mm, simulation is done by using the microwave software IE3D; to achieve the desired results. The antenna have minimum VSWR of 1.05 at a frequency of 1.897 GHz. Return loss is to be -30 dB at a frequency of 1.897 GHz. Substrate taken was glass dielectric constant 4.4 and loss tangent is 0.02. At frequency 1.897 GHz. Radiation efficiency is 89% and antenna efficiency is 89.9%. E total gain achieved is 0.203457 dBi.
