Abstract

The invention relates to a W-band horizontal-vertical waveguide conversion structure easy to process and a processing method, and belongs to the technical field of radar antenna feeders. The W-band horizontal-vertical waveguide conversion structure easy to process comprises a horizontal waveguide, a coupling slot and a vertical waveguide, the horizontal waveguide is extended by 0.5 times of the wavelength of the horizontal waveguide, so that the electrical properties such as insertion loss and port standing wave of the original structure are basically unchanged, and the W-band horizontal-vertical waveguide conversion structure is easy to process and weld when being applied to a W-band.

Description

technical field [0001] The invention belongs to the technical field of radar antenna feeders, and in particular relates to a horizontal-vertical waveguide conversion structure in an antenna feeder, which is used to convert a horizontal waveguide into a vertical waveguide to facilitate connection with a vertical transceiver device. Background technique [0002] The horizontal-vertical waveguide conversion structure converts the electromagnetic field transmitted in the horizontal waveguide into the electromagnetic field in the vertical waveguide through the coupling slot. The coupling slot is located at the center of the vertical waveguide, parallel to the broad side of the vertical waveguide, and keeps a certain distance between the center and the short-circuit side of the horizontal waveguide. The size of the coupling slot and the distance between its center and the short-circuit side of the horizontal waveguide jointly determine the insertion loss of the conversion structur...
