In this article, a printed ring shaped monopole ultra‐wideband antenna with band‐notched feature is presented and investigated. To get the band‐notched characteristic, a quarter wavelength tuning stub is embedded into the ring radiator. The measured results show that the proposed antenna meets the requirement of wide working bandwidth of 3.1–10.6 GHz with VSWR < 2, while avoiding the interference with the wireless local area network band (5.150–5.825 GHz). The transfer function (amplitude of S 21 /group delay) and time domain characteristic (fidelity/power spectrum density) are also studied in this article. The proposed antenna has a compact size, good radiation characteristics, ultrawide bandwidth, and good time‐domain behaviors to satisfy the requirement of the current wireless communications systems. © 2012 Wiley Periodicals, Inc.
