rectangular microstrip patch antenna at resonant frequency of 2.4 GHz. These types of microstrip antennas give high performance, robust in design and easy to fabricate. Patch elements are placed on FR-4 epoxy substrate of relative permittivity 4.4 kept at a substrate height of 1.6 mm. Simulation results are presented using HFSS version 13.0. The return loss obtained is - 22.1__, and the impedance bandwidth achieved is 37%, VSWR is 1.15 and the gain is 2.55__ at the centre frequency of 2.4 GHz.
