Embodiment 2

[0037] Such as figure 1 , Figure 4 , Figure 5 As shown, the difference between the present embodiment and the first embodiment is that the axial cross-section of the shape of the coupling cavity 3 is the original shape. The angle between the coupling hole 2, the coupling cavity 3 and the coupling ring 4 and the axial direction of the main waveguide 1 is greater than 5 degrees.

Embodiment 3

[0039] Such as figure 1 , figure 2 As shown, the difference between the present embodiment and the first embodiment is that the shape of the coupling cavity 3 is rectangular. The angle between the coupling hole 2, the coupling cavity 3 and the coupling ring 4 and the axial direction of the main waveguide 1 is greater than 5 degrees.

[0040] The main difference between the above three solutions is that a metal ridge is added to the bottom of the main waveguide 1 , that is, a metal ridge 8 is connected to the inner wall of the main waveguide 1 away from the coupling hole 2 . Whether the shape of the coupling cavity 3 is rectangular or rectangular, whether the shape of the coupling hole 2 is rectangular or rectangular, whether there is an angle between the coupling hole 2 , the coupling cavity 3 and the coupling ring 4 and the main waveguide 1 . In the specific implementation process, the size of the coupling hole 2, the size and shape of the coupling cavity 3, the size of th...

Abstract

The invention discloses a waveguide ring coupler comprising a main waveguide, a coupling hole is formed in the side wall of the main waveguide, a coupling cavity is connected with the position of the coupling hole of the main waveguide, a coupling ring is arranged in the coupling cavity and connected with a coaxial port, moreover the coaxial port is arranged outside the coupling cavity, besides, transition steps are connected with the two ends of the main waveguide, and standard waveguides are arranged at one ends, far from the main waveguide, of the transition steps. Due to the fact that a main wire is of a waveguide structure, an auxiliary wire is coaxial, and a coupling mechanism is achieved by the single round hole, the waveguide ring coupler has the advantages of being simple in circuit, novel in structure, convenient to process and assemble, dispensed with tuning, moreover small in insertion loss, good in standing wave of the port, high in reliability, and specially suitable for the occasion of high-power bi-direction weak coupling degree measurement and indication.

Description

technical field [0001] The invention relates to a waveguide ring coupler, in particular to a broadband single-hole waveguide ring coupler. Background technique [0002] A hole is made in the wall of a waveguide to allow the signal to be coupled out of the waveguide, thus making it possible to make a directional coupler. The waveguide directional coupler commonly used at home and abroad usually adopts hole-slot coupling, and one or more holes / slits are opened on the common waveguide wall to couple the microwaves in two adjacent waveguides. A directional coupler with a corresponding power distribution ratio can be obtained by adjusting the hole / slot size and its position. A major disadvantage of this directional coupler is its narrow operating bandwidth. Contents of the invention [0003] The object of the present invention is to provide a waveguide ring coupler capable of good coupling flatness and directivity within the full bandwidth of the waveguide. [0004] In orde...
