Problems solved by technology

[0008] However, in terms of processing of circular waveguides, compared with rectangular waveguides, the fundamental mode of circular waveguides has the problem of polarization deflection, that is, when the processing of circular waveguides is not perfect or there is a small inhomogeneity in the waveguide, the main wave of circular waveguide The polarization plane of the type field structure is very easy to rotate, which will lead to uneven distribution of the radiation field along the longitudinal direction of the waveguide

Abstract

The invention discloses a composite copper layer polyvinyl chloride leakage waveguide feeder line and a manufacturing method thereof. The composite copper layer polyvinyl chloride leakage waveguide feeder line, in structure, radially comprises a copper foil layer, a polyvinyl chloride hard circular tube and a flame retardant protection layer in sequence from an inner diameter to an outer diameter,wherein the outer surface of the polyvinyl chloride hard circular tube is also provided with a plurality of slots along the length direction; and the opposite side of the slot is a joint place of a ridge structure. The composite copper layer polyvinyl chloride leakage waveguide feeder line is scientifically designed, and high-frequency communication requirements, signal stability, light weight, and easy installation under a complicated environment 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 leaky waveguide feeder and a manufacturing method thereof. Background technique [0002] Currently, radio wave coverage systems applied in confined spaces are roughly divided into waveguide antennas and leaky wave antennas. The waveguide shows that while the energy is transmitted along the waveguide, it is coupled and laid outward through the pores on the outer wall of the waveguide, thereby forming a stable electromagnetic waveguide channel around the waveguide. Different from the application requirements for long-distance radio wave coverage with waveguides, leaky-wave antennas, as typical traveling-wave antennas, usually have the characteristics of low cost, high radiation efficiency, and energy concentrated in one place in the space to radiate outward, which can meet short-distance and small-range reception requireme...
