Abstract

The invention relates to an elliptical waveguide load. The elliptical waveguide load comprises a flange plate, a waveguide cavity, an absorber and a tail cover plate, wherein the flange plate and thetail cover plate are respectively arranged at two ends of the waveguide cavity, and the absorber is arranged in the waveguide cavity after being fixed on the tail cover plate. The elliptical waveguideload is characterized in that the section of the waveguide cavity is elliptical, and the absorber is conical. Compared with the prior art, the assembly structure is simplified, the advantages of saving the installation space and being low in cost are achieved, and the elliptical waveguide load is more suitable for application scenes with insufficient space resources such as tunnels or tracksides;in addition, an assembly using the elliptical waveguide load is lower in reflection coefficient and more excellent in voltage standing-wave ratio performance.

Description

technical field [0001] The invention relates to the technical field of waveguide loads, in particular to an elliptical waveguide load. Background technique [0002] The waveguide load is one of the common components in the microwave radio frequency system, and its function is to improve the line matching condition and maintain the traveling wave state of the system. The waveguide load consists of a certain length of waveguide cavity embedded with microwave absorbing material. In order to match the front-end waveguide interface and ensure better electrical performance, the load interface is usually a standard rectangular interface that conforms to the national standard (GB11443.2), such as figure 1 shown. [0003] In microwave radio frequency systems, elliptical interfaces (non-standard) are also widely used. For example: elliptical waveguide is one of the earliest transmission line types used to transmit microwave signals, and it is still widely used in high-power systems...
