A novel broadband design procedure for balanced compact planar tapered slot antenna

In this paper, we propose a new technique to design the entire antenna on one side of the substrate with a broad impedance bandwidth performance. This method can be extended to any planar balanaced antenna. As an example, an eagle feed Vivaldi antenna was designed for one sided TSA, using the propopsed technique. Impedance bandwidth of fabricated antenna is from 2.1 to 18.0 GHz.
