Abstract

The invention relates to a small type isofacial polarizer and belongs to the technical field of electronic communication. The small type isofacial polarizer is adaptable to military and civilian microwave communication, satellite communication, radar equipment, aerospace and target tracking. The small type isofacial polarizer comprises a polarization separator, a first rectangular waveguide, a polarization adjustment motor, a first connector and a figurative coupling probe. The polarization separator comprises a second rectangular waveguide, a round waveguide, a straight probe, a third rectangular waveguide and a second connector. The polarizer has the advantages that length of a Ku frequency band component is 55mm, with size small and weight light; height of a horizontal port and the height of a vertical port of the polarizer are same so as to achieve compactness and integration; phase equalization of the horizontal port and the vertical port is high, with work performance stable, the polarizer can be widely applied to the antenna feed system which is high in phase equalization and has high requirements on the phase equalization of the horizontal port and the vertical port.

Description

technical field [0001] The invention relates to a small isophase polarizer, which belongs to the technical field of electronic communication, in particular to a small isophase polarizer used for military and civilian microwave communication, satellite communication, radar equipment, aerospace and other target tracking. Background technique [0002] With the development of modern communication, remote control, and telemetry technology, the demand for vehicle-mounted, ship-borne, airborne, and missile-borne communications is increasing. High performance and miniaturization of microwave devices are becoming increasingly important. The existing polarizer generally achieves the polarization distribution and the matching of the antenna polarization angle through the rotation of the circular waveguide, which has a large moment of inertia and is difficult to miniaturize. [0003] Even if other structures are used to solve the problems of large moment of inertia and high motor power...
