Analysis and design of microstrip antenna array for S-band applications

In this paper, microstrip antenna arrays of two and four element are designed using commercially available low cost FR4 material to operate at frequency 2.5GHz. Antenna properties are analysed using IE3D simulation tool. Simulation results show that gain of two element array is 5.5dB and gain of four element array is 9.3dB. Beam width of two element and four element array are 45° and 35° respectively. The simulated results are verified experimentally by fabrication of the designed antenna arrays using FR-4 substrate material, results are in good agreement with the simulated results.
