Abstract :
This paper presents a compact antipodal Vivaldi antenna for UWB allocation with band dispersion characteristics. The main purpose of this design is the reduction of three parameter such as transient distortion, reflection co-efficient & surface wave loss. The proposed antenna has the capability to operate over the bandwidth 3-11GHz at return loss <; -10 dB, except the bandwidth of 5-6GHz for WLAN. By cutting Ω-shaped slot in the radiating patch frequency band notch created. The antenna is successfully designed and simulated, it showing broadband matched impedance, stable gain and radiation pattern over a operating bandwidth.
