An ultra‐wideband (UWB) planar metal‐plate monopole antenna with a band‐notch characteristic is presented. The proposed planar metal‐plate monopole antenna is embedded with an inverted U‐shape slot, whose length is selected to be a half‐wavelength at the desired notched frequency. By adjusting the slot length, the notched frequency band within the antenna's operating bandwidth can be easily controlled. A design example for an UWB (3.1–10.6 GHz) planar metal‐plate monopole antenna with a notched frequency band at 5 GHz is demonstrated. © 2005 Wiley Periodicals, Inc.
