High-Power Wideband Transmission of Modulated Signals Using an Integrated Class-E Active Electrically-Small Antenna

The proposed active electrically-small antenna design can radiate wideband HF signals with bandwidths of 24 kHz or more, with total efficiencies up to 80%, and radiated power levels approaching 100 W, by integrating a highly-efficient, class-E switching circuit with the antenna.
