Nested-Cone Transformer Antenna

US Patent:
5019832, May 28, 1991
Filed:
Oct 18, 1989
Appl. No.:
7/423174
Inventors:
Carl A. Ekdahl - Santa Fe NM
Assignee:
The United States of America as represented by the Department of Energy - Washington DC
International Classification:
H01Q 136, H01Q 1304
US Classification:
343774
Abstract:
A plurality of conical transmission lines are concentrically nested to form n output antenna for pulsed-power, radio-frequency, and microwave sources. The diverging conical conductors enable a high power input density across a bulk dielectric to be reduced below a breakdown power density at the antenna interface with the transmitting medium. The plurality of cones maintain a spacing between conductors which minimizes the generation of high order modes between the conductors. Further, the power input feeds are isolated at the input while enabling the output electromagnetic waves to add at the transmission interface. Thus, very large power signals from a pulse rf, or microwave source can be radiated.
