Abstract
A waveguide adapter is arranged between a rectangular waveguide with a single cross-section and an elliptical waveguide which allows for the propagation of a fundamental wave type and higher wave types. The adapter includes a longitudinal channel which allows for the propagation of higher types of waves at least on one part of the length thereof and consists of various stages with different cross-sections. The adapter also has waveguide gates which are used to couple higher waves of the elliptical waveguide. The stages of the waveguide adapter in which the higher wave types are propagated have an elliptical cross-section.
Claims10
A waveguide adapter for low reflection transmission of electromagnetic energy between a rectangular waveguide having a single cross-section for permitting propagation of a fundamental wave type, and an elliptical waveguide for permitting propagation of the fundamental wave type and higher wave types, comprising:
- a longitudinal channel for permitting propagation along a direction of transmission of the higher wave types on at least a part of a length of the longitudinal channel, the longitudinal channel having a plurality of stages of different cross-section following in succession in the direction of transmission, and waveguide gates for coupling to the higher wave types of the elliptical waveguide, said stages in which the higher wave types are capable of propagation having an elliptical cross-section.
An arrangement, comprising:
- a transport waveguide, and at least one waveguide adapter for low reflection transmission of electromagnetic energy between a rectangular waveguide having a single cross-section for permitting propagation of a fundamental wave type, and an elliptical waveguide for permitting propagation of the fundamental wave type and higher wave types, the adapter including a longitudinal channel for permitting propagation along a direction of transmission of the higher wave types on at least a part of a length of the longitudinal channel, the longitudinal channel having a plurality of stages of different cross-section following in succession in the direction of transmission, and waveguide gates for coupling to the higher wave types of the elliptical waveguide, said stages in which the higher wave types are capable of propagation having an elliptical cross-section, and the transport waveguide having a cross-section congruent with one of the stages connected to the transport waveguide.
