摘要

A novel triple-band polygonal shaped slit rectangular patch antenna with defective ground structure (DGS) is proposed for WLAN and WiMAX applications. The proposed probe-fed antenna consists of a rectangular patch, zig-zag shaped slit, dual T-shaped slits on both sides and circular dumbbell shaped defected ground. The designed antenna can generate three separate resonant frequencies to cover both the 2.45/5.28 GHz WLAN bands and the 3.5 GHz WiMAX bands while maintaining a small overall size of 40 mm x28 mm x 3.175 mm. The location and dimension of loaded polygonal slit is obtained with the aid of interfacing a genetic algorithm (GA) model with an lE3D simulator. The results obtained from simulated antenna show 5.23% impedance matching bandwidth at 2.29 GHz, 1.14% at 3.5 GHz, 5.17% at 4.64 GHz. The antenna is experimentally tested, which gives good radiation patterns and sufficient antenna gains over the operating bands.
