Abstract
In this work, Multislot rectangular Microstrip patch antenna with Defected ground structure (DGS) for Ultra Wide Band (UWB) wireless applications has been proposed. The antenna with patch dimensions 14.5 x 15mm2 in FR-4 substrate with 50 ohm feed line is presented. The proposed antenna is designed to have rectangular patch with a circular slot at each corner and Multislot DGS plane. The high frequency structure simulator (HFSS) is used to design and simulate the antennas performance over the different frequency ranges. The simulated bandwidth is 3.5 – 11.7 GHz with Return Loss is ≤ -10dB and VSWR less than 2. From the simulated results, it is clear that the proposed antenna is well suited for UWB applications.
