A coplanar waveguide (CPW) fed ultra-wideband antenna is proposed for UWB applications. The proposed antenna consists of circular monopole with single complementary split ring resonator (CSRR) slot and reduced ground plane. The overall size of an antenna is 20 × 25 × 1.6 mm³. The prototype antenna is designed, fabricated and tested. It provides good return loss characteristics and radiation pattern. The measured −10 dB impedance bandwidths are 1.06 GHz (3.9–4.96 GHz) and 4.5 GHz (6.7–11.2 GHz) with resonance frequencies at 4.4 and 9 GHz, respectively. An appropriate dimension of CSRR slot has been etched on patch to notch 5–6 GHz band to avoid interference with WLAN and WiMAX devices which is one of the crucial issues to be solved in UWB antenna. Parametric studies on width of ground plane and dimension of CSRR slot are done to investigate the effect of various geometrical values on antenna characteristics. The simulated and measured results of the antenna are in close agreement with each other which will confirm the applicability of the proposed antenna. © 2017 Wiley Periodicals, Inc.
