A wideband rectangular patch antenna [1] is designed for wireless local area network (WLANs) applications. These antennas operate for 4-7 GHz ISM band, and wideband applications. The antenna has the dimensions of 20 mm by 15 mm by 1.8 mm on FR4 substrate with dielectric constant 4.4. The substrate height is increased in each antenna to enhance the bandwidth. All dimensions are same in each antenna. The antenna is simulated by Ansoft Higher Frequency Structure Simulator (HFSS) software which is finite element method based simulator. After simulation the antenna performance characteristics such as, input impedance, return loss, Impedance band width, percentage bandwidth and polar plot are obtained.
