Abstract
The article proposed and studied a compact coplanar waveguide‐feed antenna for WiMAX applications. In this design, using notches on the ground plane and trapezoid‐feed line is to generate broadband operation of 10‐dB return loss from 1.95 to 6.55 GHz. Furthermore, embedded a narrow slit etching on the radiation patch accounts for triple‐band operation of 1.68–2.71 GHz, 3.26–4.06 GHz, and 5.03–6.24 GHz. It plays a role as a filter to eliminate the undesired band. The proposed antenna with a band‐reject characteristic is calibrated for WLAN/WiMAX applications which covers the band from 2.4 to 2.7, 3.3 to 3.8, and 5.15 to 5.85 GHz. And, this antenna has advantages of good radiation characteristics, compact size, and omni‐directional patterns. Details of the proposed antenna configuration and experimental results are discussed. © 2007 Wiley Periodicals, Inc.
