This letter presents two ultra-wideband (UWB) antennas with 3.4/5.5 GHz dual-notched hands. 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 bond (5.15-5.825 GHz), limited by IEEE 802.11b or HIPERLAN12 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 hands. Moreover, these antennas have omnidirectional radiation patterns in the H-plane (aid good gain flatness. (C) 2009 Wiley Periodicals, Inc.
