Abstract :
In this paper, we have proposed a dual-band (WLAN/UWB) antenna with open stub for WLAN/UWB applications. The designed dual-band antenna consists of a rectangular radiating patch, open stub, three steps for impedance matching, and CPW feeding. The proposed antenna is fabricated and measured. Parametric studies and radiation characteristics for the designed antenna were presented. The designed antenna has the characteristics of wide bandwidth and negligible dispersion over the UWB frequency band and omni-directional characteristics in the WLAN band.
