Abstract

The invention discloses a TE01 mode Bend structure of millimeter wave boardband plane mirror type, which comprises two symmetrical mode conversion sections, two sections of symmetrical circular waveguide structures and a quasi-optical plane mirror part, wherein the quasi-optical plane mirror part comprises a triangular prism structure part and two sections cylindrical parts which are symmetrical relative to the triangular prism structure part; and TE01 mode energy is fed in from a flange port, sequentially passes through one mode conversion sections, one circular waveguide part and the quasi-optical plane mirror part, then passes through the other circular waveguide structure and the other mode conversion section respectively symmetrical to the former circular waveguide structure and mode conversion section after passing through a reflection mirror and is transferred out from the other flange port. According to the invention, the quasi-optical plane mirror part of a plane mirror Bend is in a square waveguide way, and high-efficiency reflection of power is realized by a simple and effective mode; an adjustable mechanical structure is adopted in the reflection mirror part and can be used for effectively adjusting the transmitted efficiency; and the TE01 mode Bend structure of millimeter wave boardband plane mirror type realizes power transmission with high mode purity and high efficiency and has the advantages of low cost, easiness in processing and tuning, high efficiency, good environment adaptability, and the like.

Description

technical field [0001] The present invention relates to the technical field of millimeter-wave overmode Bend (turning), in particular to a TE with millimeter-wave broadband plane mirror structure 01 Die Bend. Background technique [0002] TE 01 The Bend structure of the mode millimeter wave transmission system has low transmission loss characteristics, and has very broad application prospects in the fields of communication, telemetry and remote control. In order to meet the requirements of small footprint, mode purity and high transmission efficiency of the transmission system, a TE 01 The mode millimeter wave overmode Bend structure has very important practical significance. [0003] At present, three common implementation forms are mainly used in the world, such as spacer type, transition to square waveguide type and plane mirror type, etc., but these three solutions have different defects, as follows. [0004] The solution of the spacer type is to bend the circular wa...
