A novel compact UWB not-concentric split ring resonator patch antenna for UWB wireless communications

A new ultra-wideband (UWB) patch antenna is proposed, based on two not- concentric split ring resonator with the ground plane printed on the same substrate face, the radiation elements of the proposed antenna are electromagnetically fed by a microstrip line with rectangular slot printed on the opposite face of the substrate. The antenna is operating the frequency band ranging from 3.56 GHz up to 16GHz. The radiation pattern plots are also presented and discussed in this paper. The entire antenna occupies only a small volume of 30mm × 31.5mm × 1.5mm. A prototype of the optimized antenna was fabricated and measured. Measurement and simulation results show a very good agreement. © 2015 IAMOT.
