Abstract

The invention discloses a truncated-cone matching coaxial waveguide orthogonal mode coupler, and belongs to the technical field of wireless communication. The coupler comprises a turnstile connector and two groups of power synthesis / distribution pipe, wherein an impedance matching structure of the turnstile connector is a metal circular truncated cone structure located at the tail end of an internal conductor of a coaxial waveguide structure. The metal circular truncated cone structure and the coaxial waveguide structure are coaxial, and the diameter of the top surface of the metal circular truncated cone structure is greater than the diameter of the internal conductor metal of the coaxial waveguide structure. The bottom surface of the metal circular truncated cone structure is connected with the bottom surfaces of four rectangular coupling waveguides. The coupler is excellent in electrical performances, is simple in processing, can achieve the constant-phase polarization separation inabout one frequency multiplication, is excellent in standing waves, isolation and plug loss, can be used for a three-band antenna system (L / S / C, C / X / Ku, K / Ka / Q), and is the important improvement of the prior art.

Description

technical field [0001] The invention relates to the technical fields of wireless communication, navigation measurement and control and radio astronomy, in particular to a coaxial waveguide orthogonal mode coupler with truncated cone matching. Background technique [0002] It has been widely used in the fields of navigation measurement and control, satellite communication, etc., and with the increase of satellite spectrum resources, dual-frequency sharing or multi-frequency sharing antennas can be used for two or more than one antenna with only a small increase in cost. Frequency band, especially when the antenna aperture is large, this method can significantly reduce the cost of the antenna system, and at the same time reduce the land use area, and facilitate the layout of user sites. [0003] In addition, with the maturity of electromagnetic simulation software and the development of coaxial turnstile coupler technology, the available bandwidth of the coaxial turnstile co...
