Abstract
Abstract: The paper gives a detailed study of how to design a microstrip patch antenna array for UWB applications by using the FR-4 substrate material. The rectangular antenna array is designed with the planar ground. The designed antenna is a rectangular shape, compact and planar for the UWB applications. The size of the antenna is 20.50×15.22 mm (width and length), which resonated at a return loss – 14 dB, -31.23 dB and -33.36 dB and the input impedance is 50 ohms. We used the box dimensions are 40 mm × 40 mm for single, 80 mm × 70 mm for 1×2 array and 100 mm × 40 mm for 1×4 array antenna. For the simulation work SONNET software is used, SONNET software is a planar 3D electromagnetic simulator and all the simulated results are shown by the graph.
