摘要：

This manuscript introduces a new design of multi-resonance monopole antenna for Ultra-Wideband (UWB) applications. The proposed antenna consists of an ordinary square radiating patch and a modified ground plane with inverted Y-shaped slit and conductor-backed plane, which provides a wide usable fractional bandwidth of more than 135%. By cutting an inverted Y-shaped slit in the ground plane and also by embedding an Inverted Y-shaped conductor-backed plane in the feed gap distance, additional (third and fourth) resonances are excited and hence much wider impedance bandwidth can be produced; especially at the higher band. By obtaining these resonances, the usable lower frequency is decreased from 3.12 to 2.9 GHz, and also the usable upper frequency of the presented monopole antenna is extended from 10.3 to 14.85 GHz. The measured results show that the proposed antenna can achieve the Voltage Standing Wave Ratio (VSWR) requirement of less than 2.0 in frequency range from 2.83 to 14.87 GHz, which is suitable for UWB systems.
