A novel and compact ultra‐wideband (UWB) printed monopole antenna with extended band‐notched designs is presented. The antenna with a total size of 20 mm × 35 mm operates in a band from 3 to over 11 GHz (VSWR ≤ 2), and shows omnidirectional radiation with a low cross‐polarization in the range of the operated band. Measured results indicate that the antenna presents a notched‐band from 5.1 to 6 GHz for VSWR ≥ 3:1, which covers the wireless local area network (WLAN) band. The notched‐band is produced by an embedded resonant cell (ERC). Experimental results show that the band‐notched function can be controlled by adjusting the length of the ERC and area of the slot. © 2007 Wiley Periodicals, Inc.
