ABSTRACT:
A radiating tapered notch antenna (sometimes known as a Vivaldi antenna) is fed by a section of slotline, which in, turn is fed by a coplanar waveguide. The transition from the unbalanced coplanar waveguide to the balanced slotline is accomplished by an infinite balun, where the center conductor of the coplanar waveguide terminates on the slotline conductor opposite the ground conductor of the coplanar waveguide. One slot of the coplanar waveguide becomes the feeding slotline for the notch, and the other slot terminates in a slotline open circuit. All of the elements of the system are coplanar.
