Designing Vivaldi antenna using Fr4 substrate / Johana Md Johari

This thesis represents a study of tapered slot Vivaldi antenna which is one of the ultrawideband(UWB) antennas. The antenna was designed by using FR4 substrates with the value of relative dielectric constant equal to 4.7. The antenna performance was analyzed during the simulation process using CST M...
