Abstract
A single Vivaldi antenna plate (half Vivaldi antenna) over a ground plane can be used to achieve a 50-ohm impedance, or two or more single plates over a ground plane to achieve other impedances. Unbalanced 50-ohm transmission lines, e.g., coaxial cables, can be used to directly feed the antenna.
