Abstract :
An antipodal Vivaldi antenna for UWB applications is presented in this paper. The proposed antenna is designed with simple structure but presents very good plot impedance characteristic. In addition, the antenna offers high gain and flat gain in the operating bandwidth from 3.1 GHz to 10.6 GHz. The antenna design simulation has been performed by using the commercially available simulation software HFSS 14. The antenna is fabricated on popular substrate FR4 with a dielectric constant of 4.4 and thickness 1.6 mm. The fabricated antenna has been tested for its return loss and directional pattern, and compared with simulated results.
