An M‐shaped monopole‐like slot Ultra wideband (UWB) antenna is proposed for UWB applications. The proposed antenna usages, an M‐shaped radiator in place of the conventional monopole patch antenna to achieve UWB frequency. The ground plane is also modified by cutting rectangular slots. Therefore, the ground plane works like a radiator that resonates at lower band of UWB. The antenna is practically fabricated and simulated. Measured results show a good agreement with simulated results. The prototype with compact overall size of 36 mm × 36 mm × 1.6 mm achieves good impedance matching, constant gain, and stable radiation patterns over an operating bandwidth of 2.38–12.40 GHz (10.02 GHz).
