摘要：

A microstrip-fed wideband antenna with defected ground structure is proposed for WLAN and WiMAX band applications. The proposed antenna uses an annular ring radiator which is encircled by a rhombus shaped strip and the defected ground plane. The ground plane is cambered shaped and cut out by rectangular-shape slot and thus forms a defected ground structure. The parametric study is carried out to study the effects of varying dimensions on the antenna performance. To validate simulation results of the design a prototype is fabricated on the commercially available FR4 material. Measured results shows a good agreement with the simulated results. It is found that the antenna shows wide bandwidth of 86.71% (2.4-6.0 GHz) which covers entire WLAN and WiMAX bands. Thus the proposed antenna is well suitable for WLAN/WiMAX applications.
