Hollow microwave guide for image-line junction - has horn radiator flare on hollow waveguide sided end, to reduce low transmission loss

摘要

The guide is used for joining a hollow microwave waveguide to an Image-line type microwave line, and the line to the waveguide, as need be, proposed junction arrangement is partic. suitable for use in the frequency range between 60 and 90 GH3 for providing transfer of a H10 wave in a rectangular hollow waveguide to a HE11 wave on the Image-Line, and is designed to provide low transmission loss in the transition process. To meet the low transmission loss requirement, the hollow-waveguide sided end of the junction arrangement, in the direction towards the microwave line, is expanded or enlarged in the shape of a horn radiator, and the microwave line sticks up into this funnel-shaped flare.
