Compact printed monopole UWB antenna loaded with non — Concentric open — Ended rings for triple band — Notch characteristic

A compact, ultra-wideband monopole antenna with triple band-notch characteristic is presented. Proposed antenna consists of an elliptical radiator for achieving UWB bandwidth. For rejecting WiMAX (3.3-3.6 GHz) and WLAN (5.15-5.3 GHz, 5.7-5.825 GHz) bands, antenna is loaded with Non-concentric open ended rings. The effective lengths for these non-concentric rings are approximately half wavelength for the respective notch frequencies. Overall surface dimension of the fabricated antenna is 25×18 mm². The proposed antenna is simulated, fabricated and tested experimentally for its performance. A good agreement between simulated and experimental results ensures the suitability of the proposed antenna for various UWB applications.
