Junction between a rectangular and a circular waveguide

摘要

A junction between a rectangular waveguide and a circular waveguide is provided, both operating in TE transmission modes. The rectangular waveguide has broad sides A and narrow sides B, one of sides A having at its middle line a circular opening being of a diameter which is equal to or less than the diameter of the circular waveguide and the other of sides A being fitted with a tapered member inside the rectangular waveguide opposite said circular opening, an end of said circular waveguide being fitted around said opening.
