Problems solved by technology
[0007] Compared with the rectangular waveguide, the circular waveguide has the above advantages, but the fundamental mode of the circular waveguide has the problem of polarization deflection, that is, when the processing of the circular waveguide is not perfect or there is a small inhomogeneity in the waveguide, the The polarization plane of the main mode field structure is very easy to rotate, which will lead to uneven distribution of the radiation field along the longitudinal direction of the waveguide, so this problem needs to be taken into account when designing the feeder

Abstract
The invention discloses a composite copper layer polyvinyl chloride waveguide feed line and a manufacturing method thereof. The composite copper layer polyvinyl chloride waveguide feed line is characterized by sequentially comprising a copper foil layer, a polyvinyl chloride rigid round tube and a flame retardant protective layer, wherein the copper foil layer is a copper-plastic composite film, the copper-plastic composite film is a two-layer structure, an inner part is a copper layer, an outer part is a plastic layer, the plastic layer of the copper foil layer is adhered to an inner wall ofthe polyvinyl chloride rigid round tube, and the copper layer of the copper foil layer is overlapped to form a joint in a ridge structure. The composite copper layer polyvinyl chloride waveguide feedline structure is advantaged in that scientific design is achieved, and requirements of high frequency communication, stable signals, light weight and convenient installation and layout in the complexenvironment can be met.
Description
technical field [0001] The invention relates to the field of communication transmission cables, in particular to a composite copper layer polyvinyl chloride waveguide feeder and a manufacturing method thereof. Background technique [0002] Currently, signal transmission feeders used in confined spaces are broadly classified into waveguide feeders and radio frequency feeders. RF feeder can meet various communication needs, but it is easily affected by the installation environment, which in turn affects the stability and effectiveness of signal transmission. The waveguide has a stable electromagnetic waveguide channel, which is not affected by the installation environment, thereby ensuring stable transmission signals. Especially in a limited space, the electrical performance of the RF feeder cable will be greatly affected due to bending, deformation, etc. In this case, using a waveguide instead of the RF feeder can form a uniform and stable signal transmission in a restricted...
