Design and Manufacture of CPW-fed Two Arc-shaped Antenna for WLAN Applications

In this paper, a dual-band arc-shaped monopole antenna for WLAN(Wireless Local Area Networks) applications. The proposed antenna is based on CPW-fed structure, and composed of two-arc shaped of radiating patch and ground plane. To obtain the optimized parameters, we used the simulator, Ansoft’s High Frequency Structure Simulator (HFSS) and found the parameters that greatly effect antenna characteristics. Using optimal parameters, the antenna is fabricated. The numerical and experiment results demonstrated that the propnosed antenna satisfied the -10 dB impedance bandwidth requirement while simultaneously covering the WLAN bands. And measured results of gain and radiation patterns characteristics displayed determined for opeating bands.
