    Abstract

    A high-power source of ultrawideband radiation with elliptical polarization of the field has been created. The source includes a monopolar pulse generator, a bipolar pulse former, a wave transformer with the power divider, and a four-element array of cylindrical helical antennas. The array was excited by bipolar pulses of the length 1 ns and amplitude 225 kV. In the experiments, the pulses of the elliptically polarized radiation with the effective potential of 440 kV and high stability at a pulse repetition rate of 100 Hz were obtained.
