Investigation of the double-y balun for feeding pulsed antennas

The double-y balun, transitioning from an unbalanced coplanar waveguide (CPW) to a balanced coplanar strip (CPS), was originally developed for use with balanced mixers. In this paper, the feasibility of this balun for feeding pulsed antennas was investigated via time-domain pattern measurements of a resistively loaded V-dipole. The need for a balun when feeding a symmetric antenna is illustrated via time-domain pattern measurements of the resistively loaded V-dipole with and without the double-y balun.
