UWB U- shaped planar printed antenna loaded with annular ring slot and tuning stubs

In this paper, a new configuration of UWB planar printed compact monopole antenna has been presented. The proposed antenna comprising of U-shaped notch loaded with tuning stubs and annular ring slot. 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 exhibits UWB for 4.32 GHz to 12.92 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 is confirmed by simulated results using Ansoft HFSS software.
