Paper Abstract

In this paper, a tunable antipodal Vivaldi antenna is presented for frequency scanning in UWB applications. The upper and lower patches of tapered slot antenna (TSA) consist of two different gradient edges from which frequency scanning function is obtained. Microstrip line of 50 Ω impedance is used for feeding the antenna. The tuning is achieved by varying the DC biasing of Ferrite substrate. The main beam of the E-plane radiation patterns at single operating frequency of 8 GHz, are -40°, 15 °, and -10 °, respectively, which clearly shows the frequency scanning function of the antenna.
