This letter presents two ultra‐wideband (UWB) antennas with 3.4/5.5 GHz dual‐notched bands. The U‐ and V‐slots are used to reject the frequency band (3.3–4.2 GHz) limited by C‐band satellite communication and Wimax systems. Another rejection band (5.15–5.825 GHz), limited by IEEE 802.11b or HIPERLAN/2 system, is obtained by using the U/V‐slot defected ground structure. Experimental results indicate that these antennas cover the entire UWB for voltage standing wave radio <2, except two notched bands. Moreover, these antennas have omnidirectional radiation patterns in the H‐plane and good gain flatness. © 2009 Wiley Periodicals, Inc.
