摘要: A plurality of conical transmission lines are concentrically nested to formn output antenna for pulsed-power, radio-frequency, and microwave sources. The diverging conductors enable a high power input density across bulk dielectric be reduced below breakdown at the interface with transmitting medium. cones maintain spacing between which minimizes generation order modes conductors. Further, feeds isolated while enabling electromagnetic waves add interface. Thus, very large signals from pulse rf, or source can radiated.
