A wideband converter of the main mode of the coaxial line into the lowest symmetric mode of a circular waveguide

Abstract

Band-pass (in a 0.5- to 10.0-GHz range) characteristics of a converter based on a coaxial conical line with a cylindrical inner conductor, which excites the TM ₀₁ mode of a circular waveguide, are theoretically and experimentally studied. It is shown that the upper frequency of the operating band of this converter is limited by the resonance excitation of the TM ₀₁ ^c mode in the coaxial conical line. Another version of the converter based on the coaxial conical line with a conical inner conductor, in which the conversion bandwidth of 95% TEM mode power into the TM ₀₁ mode power is increased to 60%, is designed.
