This paper presents an UWB planar printed compact monopole antenna comprising of U-shaped notch loaded with L-slot and tuning stubs. It has a partial ground plane to achieve an excellent impedance matching to increase the impedance bandwidth. The simulated results show that the proposed antenna exhibit UWB for 3.84 GHz to 11.61 GHz with –10dB return loss and VSWR < 2. Antenna gain and radiation pattern plots for different frequencies are also investigated. The performance characteristics of the proposed antenna are simulated using Ansoft HFSS software. Index Terms planar antenna, ultra wideband, partial ground plane.
