Zusammenfassung:ABSTRACT In this paper a coplanar waveguide (CPW) fed ultra‐wideband (UWB) circular ring monopole antenna with a modified ground plane is proposed. The dimensions of the antenna are obtained using a genetic algorithm (GA) optimization procedure. To proof the concept and validate the design antenna prototypes have been fabricated and tested. A good agreement is obtained between numerical simulation and experimental results. The input reflection coefficient is below −10 dB in the frequency range 2.52 GHz to 12 GHz, which corresponds to an impedance bandwidth of about 4.8:1, and the gain is about 3 dBi. The proposed antenna element seems to be suitable for UWB and cognitive radio spectrum sensing applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1319–1323, 2016
