Abstract

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 band are also analyzed. © 2005 Wiley Periodicals, Inc.
