A novel dual band‐notched monopole ultra‐wideband antenna is proposed, in which the parasitic strip creates one band‐notch at 5.5 GHz and the tuning stub produces another band‐notch at 3.5 GHz. The experimental results show that the proposed antenna, with a compact size of 20 × 31.5 mm 2 , has a bandwidth of 3.1–10.6 GHz with voltage standing wave ratio (VSWR) less than 2, except the bandwidths of 3.3–3.7 GHz for WIMAX and 5.15–5.825 GHz for WLAN. By changing the lengths of the parasitic strip and the tuning stub, the central frequencies of the dual notched bands can be adjusted easily. In addition, there is a little influence on a band‐notched characteristic when another is changed. © 2009 Wiley Periodicals, Inc.
