Abstract : The patent relates to an apertured metallic ground plate antenna element having a high input impedance which is driven from a lower impedance input transmission line by means of an exciter that provides broadband impedance transformation. The input transmission line is divided into two higher impedance feed lines that feed two parallel plate transmission lines. The parallel plate transmission lines are positioned in close proximity to the element aperture and are oriented to provide antenna excitation in series.
