Abstract

The invention discloses a broadband equal phase output orthogonal mode coupler, and belongs to the technical field of wireless communication. The broadband equal phase output orthogonal mode coupler comprises a turnstile joint and two sets of power combination/distribution pipelines, wherein the two sets of the power combination/distribution pipelines realizes staggered arrangement of radial pipeline sections thereof at the intersection through the length difference of axial pipelines sections. The broadband equal phase output orthogonal mode coupler is excellent in electrical performance, simple to process, capable of achieving equal-phase polarization separation within almost one double frequency, excellent in indexes such as standing wave, isolation and insertion loss, and can be applied to a dual-band common antenna system with the bands being L/S, S/C, X/Ku, Ku/Ka and the like or a transmitting and receiving common antenna system with the band being L, S, C, X, Ku, Ka and the like, thereby being an important improvement for 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 broadband equal phase output quadrature mode coupler. 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 use method can significantly reduce the cost of the antenna system, reduce the land use area, and facilitate the layout of user sites. [0003] In addition, with the maturity of the electromagnetic simulation software and the development of the turnstile coupler technology, the turnstile coupler is used more and more in the antenna feed system due to its wide...
