Abstract

A small novel ultra wideband (UWB) antenna is presented in this letter. The proposed antenna has a small size of 15 x 12 mm and provides an ultra wide bandwidth from 3.2 to 10.5 GHz with VSWR level less than 2. The impedance bandwidth of the antenna is improved by adding two notches at the bottom of patch, T slot, and slotted ground plane. Simulation is performed by using Zeland FDTD software. The measured return loss shows agree well with the simulated one. The measured radiation pattern has shown an omnidirectional pattern for the whole frequency range.
