A novel and simple design of a printed circular patch antenna for ultra‐wideband application with a band‐notched characteristic is presented. By cutting a pie‐shaped slot on the circular radiating patch, a frequency band notch will be created. The cutting pie depth contributes to the notch center frequency and notch bandwidth while the pie flare angle contributes to the notch bandwidth. It is easy to design a specific notch band range by adjusting the cutting pie size. The position of cutting pie is also investigated. Details of the proposed designs and experimental results of the constructed prototypes are presented. © 2006 Wiley Periodicals, Inc.
