Abstract

The invention discloses a cross coupler based on mode synthesis and a construction method thereof, and an impedance matching structure. The cross coupler comprises a body, wherein the cross coupler body comprises two separator polarizers, and the two separator polarizers are symmetrically cascaded to form the body. Compared with a traditional cross coupler structure, the cross coupler is characterized in that the cross coupler is formed by symmetrically cascading two partition plate polarizers, and the cross coupler is obtained by superposing the separator polarizers under two excitation modes, namely an odd mode and an even mode, by adopting a mode synthesis method; and the cross coupler not only has the advantages of wide frequency band, low insertion loss and high isolation, but also issimple and compact in structure and easy to process, so the cross coupler based on a rectangular waveguide design can be widely applied to millimeter wave bands and can meet requirements of full-performance tests and basic performance tests of the cross coupler.

Description

technical field [0001] The invention relates to the technical field of millimeter wave communication, in particular to a cross coupler based on mode synthesis, a construction method, and an impedance matching structure. Background technique [0002] In recent years, as countries around the world have successively released the fifth-generation mobile communication (5G) millimeter-wave spectrum planning, the research and development and industrialization of millimeter-wave communication on a global scale have entered a rapid development track. Compared with traditional microwave communication, millimeter wave can effectively solve the problem of spectrum tension in microwave wireless communication below 6 GHz due to its short wavelength and wide bandwidth, and realize ultra-high-speed wireless communication. However, the atmospheric transmission loss of millimeter waves is relatively high, and antennas with high gain characteristics are usually required in millimeter wave comm...
