Abstract
An ultra-wideband, large-current radiator consisting of a ground plane and two electric monopoles: a wide radiating monopole orthogonal to the ground plane, and a thin monopole orthogonal to the ground plane and normally displaced from the wide monopole. The frequency-independent low impedance of the antenna allows a small voltage to generate a large current. The wide radiating monopole may be a flat sheet, or a sheet of parallel bars. Shielding by the wide monopole suppresses radiation from the thin monopole into a sector of space into which the monopole radiation characteristic of a well-formed impulse in response to a voltage step is desired. In one preferred embodiment, two parallel flat sheets or a conducting cylinder is used as the wide radiating monopole, further shielding radiation from the thin monopole.
