Abstract :
A compact CPW fed antenna with band notch characteristic is presented in this paper. It has compact size of 35 × 30mm and has ultra wide band operation. A `C´ shaped slot was introduced to achieve band notch from 5 GHz to 6 GHz to avoid interference from WLAN. The proposed antenna has ultra wide band frequency range from 3.1 GHz to 12.3 GHz for return loss below -10 dB, except for frequency stop band from 5 GHz to 6 GHz. Details of antenna are presented with parametric study for Ultra Wideband Applications. The bandwidth is varied by varying the width W7 and height L7 of inner tuning stub and Ultra Wideband width is obtained. The antenna is Omni directional in operating bandwidth and it has good radiation efficiency. The fundamental parameters such as return loss, VSWR, radiation pattern are obtained, which meet standard specifications. Method of moments based IE3D simulator is used to analyze this antenna.
