摘要: In this article, a low-cost, compact printed microstrip-fed circular monopole ultra-wideband antenna with dual band-notched function is proposed.By embedding C-shaped slot on the radiating patch and pair of L-shaped slots rectangular ground patch, band notched characteristics around 3.5 GHz for WiMAX 5.5 wireless local-area network (WLAN) can be obtained. The proposed designed, fabricated, tested. measured results show UWB impedance bandwidth notch, stable radiation patterns, constant gain. antenna, dimension 24 × 36 mm2, operates over frequency from 2.5 to 10.6 S11 ≤ −10 dB, except notch bands 3.3–4.2 5.1–5.9 GHz. Group delay transfer indicate that has good transient response. addition, patterns are nearly omnidirectional in H-plane typical monopole-like E-plane. © 2011 Wiley Periodicals, Inc.
