SRR- and CSRR-loaded ultra-wideband (UWB) antenna with tri-band notch capability

Abstract

In this study, a novel ultra-wideband antenna with a tri-band notch capability is proposed. The proposed antenna can reject worldwide interoperability for microwave access (WiMAX, 3.3–3.7 GHz), wireless local area network (WLAN) IEEE802.11a/n (5.15–5.825 GHz), and international telecommunication union (ITU, 8.025–8.4 GHz) bands. The band notch capability is achieved by merely a split ring resonator (SRR) and complementary-SRR (CSRR) patterns. The SRR under the radiating patch, the CSRR loaded on the radiating patch, and the CSRRs on the ground of the CPW feeding reject the WiMAX, WLAN, and ITU bands, respectively. The simulation and measurement results demonstrate the performance of the proposed antenna.
