By embedding a simple arc-shaped slot in a circular-disk monopole antenna, an ultra-wideband (UWB, 3.1-10.6 GHz) operation with a controlled notched frequency band can be obtained. The arc-shaped slot is placed close to the boundary of the circular-disk monopole and has a length of about one-half wavelength of the desired notched frequency. The proposed slotted circular-disk monopole antenna showing UWB operation with a notched frequency band for rejecting the 5.8-GHz. WLAN band is demonstrated. The effects of the dimensions of the arc-shaped slot on the notched frequency bond are also analyzed. (c) 2005 Wiley Periodicals, Inc.
