Abstract

683,352. High-frequency electric filters. STANDARD TELEPHONES & CABLES, Ltd. Jan. 5, 1951 [March 27, 1950], No. 389/51. Class 40 (viii). A high-frequency filter comprises a single conductor having a number of axially separated enlarged conductor sections extending outwardly in axial symmetry about the conductor. It is intended for use with a transmission line formed from a single conductor with insulation thereon. The energy in this form of line is transmitted by electromagnetic waves in a region closely surrounding the conductor. In the first construction shown, the enlarged sections 4 decrease in diameter towards each end of the filter to match the filter better with its associated lines. At one end the filter may be connected to the inner conductor 6 of a coaxial line. The first section 5 of the filter is embedded in insulation which tapers at the same angle as the line of decrease of sections and this is also roughly the slope of the flare of the outer conductor of the coaxial which is not shown. In an alternative construction, which is joined to a wave-guide or coaxial line containing dielectric 14, the end section 15 may itself be tapered as shown.
