Abstract
A high-frequency signal transmission system for use as a microwave antenna or filter has a plurality of cascaded conical or planar inner conductors each having a unitary exponential gradient, a pair of circular lines or impedance-matching lines having identical dimensions and connected respectively to opposite ends of the conical or planar inner conductor for providing a predetermined characteristic impedance, and a cylindrical or rectangular tubular outer conductor covering the conical or planar inner conductor and the circular or impedance-matching lines with a cavity defined between the conical or planar inner conductor and the cylindrical or rectangular tubular outer conductor.
Claims22
A high-frequency signal transmission system comprising:
- at least one conical inner conductor having a unitary exponential gradient, and having a normalized characteristic impedance at its center represented by two cascaded circuits of a conjugate-matched uniform-impedance line;
- a pair of circular lines having identical dimensions and connected respectively to opposite ends of said conical inner conductor for providing a predetermined characteristic impedance;
- and
- a cylindrical outer conductor covering said conical inner conductor and said circular lines with a cavity defined between said conical inner conductor and said cylindrical outer conductor.
A high-frequency signal transmission system comprising:
- at least one planar inner conductor having opposite sides each having a unitary exponential gradient, and having a normalized characteristic impedance at its center represented by two cascaded circuits of a conjugate-mated uniform-impedance line;
- a pair of impedance-matching lines having identical dimensions and connected respectively to opposite ends of said planar inner conductor for providing a predetermined characteristic impedance;
- and
- a rectangular tubular outer conductor covering said planar inner conductor and said impedance-matching lines with a cavity defined between said planar inner conductor and said rectangular tubular outer conductor.
