The article proposed and studied a coplanar waveguide CPW‐feed antenna. In this design, broadband structure covers from 2.43 to 7.2 GHz, which has impedance bandwidth above of 100%. The resonant frequency was obtained by adjusting the length of notch and the distance between radiation patch and ground plane. Furthermore, embedded the symmetrical slits close to a quarter wavelength on the rhomb patch and ground plane, respectively. It plays a role as a filter to eliminate the useless band. The proposed antenna with band‐rejection characteristic is calibrated for WiMAX (worldwide interoperability for microwave access, IEEE 802.16a/d/e/2004) applications which cover the band from 2.495 to 2.69 GHz, 3.3 to 3.8 GHz, and 5.25 to 5.85 GHz. And, this antenna has advantages of good radiation characteristic, compact size, and omni‐directional patterns. Details of the proposed antenna configuration and the experimental results are discussed. © 2007 Wiley Periodicals, Inc.
