Abstract: In this article, a compact Mickey shaped monopole UWB antenna is presented with dual notch band characteristics. The proposed antenna VSWR (<2) and return loss (<-10 dB) results have been verified by EM simulator and the measured impedance bandwidth covers from 2.88 GHz to 12.11 GHz which confirms the bandwidth. Furthermore, the two notched bands, i.e., WiMAX (3.3-3.7 GHz) along with C band (3.7-4.2 GHz) and WLAN (5.15-5.825 GHz) are band rejected so that the interference is mitigated in the existing wireless system. The proposed antenna is fabricated with compact dimensions of 20 × 20 mm² = 400 mm² on FR4 substrate with permitivity 4.4 and thickness of 1.6 mm. The measured gain and radiation characteristics of proposed antenna provide best results showing omni-directional pattern in H-plane and dipole like pattern in E-plane.
