A new novel compact planar UWB antenna

In this paper a simple structure of Ultra Wideband (UWB) antenna is proposed. The antenna is designed on FR4 substrate and fed with 50 ohms microstrip line. The designed antenna uses the V shaped slot configuration on the trapezium shaped patch with partial curved ground plane. The antenna exhibits a -10 dB return loss bandwidth over the entire frequency band. The proposed antenna has bandwidth of 9.2 GHz from 2.3 GHz up to 11.5 GHz range. By this way, the antenna can achieve wideband characteristic and very small size. This paper discusses the antenna parameters such as return loss, radiation pattern and power gain. Having wideband characteristic, compact and planar structure, the antenna is suitable for UWB wireless communication applications. Details of the proposed antenna design, simulated and measured results are presented and discussed.
