Taper waveguide rotating stub

Abstract

The invention provides a taper waveguide rotating stub which comprises a first flange, a first circular waveguide, a waveguide converter, a rectangular waveguide, a second circular waveguide and a second flange, wherein the first and second circular waveguides are perpendicular to each other; the diameter of the first circular waveguide is greater than the height of the rectangular waveguide; a circular port adapted to the diameter of the first circular waveguide is formed in one end of the waveguide converter, and a rectangular port adapted to the height of the rectangular waveguide is formed in the other end of the waveguide converter; the first flange is arranged at one end of the first circular waveguide; the other end of the first circular waveguide is connected with the circular port of the waveguide converter; the rectangular port of the waveguide converter is connected with the lateral surface of the rectangular waveguide; the second flange is arranged at one end of the second circular waveguide; the other end of the second circular waveguide is connected with the end face of the rectangular waveguide; the second circular waveguide and the rectangular waveguide are coaxially arranged. According to the taper waveguide rotating stub, a transmission path of electromagnetic waves in a waveguide channel can be shortened.

Description

technical field [0001] The invention relates to the technical field of electromagnetic wave propagation, in particular to a tapered waveguide rotating branch. Background technique [0002] In the microwave signal transmission system, in order to enable the antenna to search, track and measure targets at all times during work, it is often required that the azimuth angle of the antenna can be adjusted by 360 degrees, and the elevation angle can be adjusted by ±90 degrees. Therefore, a waveguide rotating branch must be installed between the network and the feed source to ensure the effective transmission of microwave signals. [0003] The waveguide rotating branch can be divided into rectangular waveguide and circular waveguide according to the shape of the waveguide section. Although there are many different waveguide forms, the traditional waveguide rotating branch is composed of waveguides that overlap and connect with each other, which will cause The electromagnetic wave h...

Problems solved by technology

[0003] The waveguide rotating branch can be divided into rectangular waveguide and circular waveguide according to the shape of the waveguide section. Although there are many different waveguide forms, the traditional waveguide rotating branch is composed of waveguides that overlap and connect with each other, which will cause The propagation path of the electromagnetic wave in the waveguide channel is long, so it is easily affected by the restriction and reflection of the inner wall of the waveguide, resulting in problems such as poor impedance matching, poor return loss index, and large signal power loss.
