Abstract :
This paper presents the results of a CPW-coupled-fed elliptical UWB monopole antenna (CCFEUMA) with a simple dual-band notched design for the WLAN Band. The antenna has a large bandwidth covering the frequency band from 2.5 to 14.6 GHz with the return loss larger than 10 dB. Two band notches at the lower (5.15-5.35 GHz) and higher (5.725-5.825 GHz) WLAN band are realized by cutting two half-elliptical arc-slots on the radiator. The return loss, radiation pattern, peak gain and efficiency of the antenna are studied using computer simulation and measurement.
