Abstract

The invention belongs to the technical field of wireless communication, in particular to a waveguide polarization device and a combiner of the waveguide polarization device. The waveguide polarization device comprises a rectangular waveguide located on a central axis, four small waveguides are embedded on four wide edge corners of the rectangular waveguide, wherein the cross sections of the four small waveguides are rounded rectangles, and the four small waveguides are symmetrical in pairs relative to the rectangular waveguide. The combiner comprises the polarization device and two combiner rectangular waveguide openings, wherein the polarization device is located on an identical central axis and symmetrically and rotatably arranged relative the central axis, and the polarization device is located between the two combiner rectangular waveguide openings. The waveguide polarization device is simple in structure and excellent in performance, almost no insertion loss exists after the waveguide polarization device is mounted, return loss is extremely low, the polarization device does not need to be rotated or replaced, two polarization modes of horizontal polarization and vertical polarization can be achieved simultaneously, in engineering use, workload of constructors on a tower can be reduced, construction cost is reduced, and meanwhile quality risks are also reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a waveguide polarization device and a combiner thereof. Background technique [0002] Rectangular waveguide is an important transmission mode of communication system. In engineering, low insertion loss and low return loss are often required for rectangular waveguide. However, the existing rectangular waveguide polarization changing devices are often complex in structure, poor in performance, and difficult to process. high cost. During the use of the combiner, it needs to be docked with the antenna. The antenna may be horizontally polarized or vertically polarized. Therefore, it is necessary to adjust the polarization of the antenna port of the combiner to match the antenna. There are two known adjustment methods: one is to replace the polarization device, and the other is to rotate the polarization device. There are problems in these two methods. When...
