This article describes the performance evaluation of Rectangular microstrip patch antenna using different feeding techniques such as Coaxial probe feed, Inset feed and Microstrip line feed. Three antennas are designed at frequency 2.44 GHz (Bluetooth). The antenna is designed by using substrate FR-4 which has dielectric constant 4.4, thickness 1.6 mm and loss tangent 0.02. Return loss, VSWR, Smith chart, Bandwidth are simulated and compared all these parameters for different feeding techniques. Simulation is done by using Ansys Electronics HFSS suite 19.2.
