Abstract

The invention discloses a leakage circularly polarized waveguide, which comprises a closed short-circuit end, a coaxial waveguide, a matching unit and a feed unit which are sequentially arranged from back to front, the coaxial waveguide comprises a first inner conductor, a first insulating layer and a first outer conductor which are sequentially distributed from inside to outside, the first inner conductor is coated with the first insulating layer, and the first insulating layer is coated with the first outer conductor; a slot array is arranged on the outer surface of the first outer conductor in a matrix mode in the signal transmission direction, the slot array is composed of a plurality of groups of slot array elements arranged in the length direction of the outer surface of the first outer conductor, and each group of slot array elements is of an annular structure formed by surrounding a plurality of slot units in the circumferential direction. Each gap unit is composed of a first gap and a second gap which are arranged in pairs, and the first gap and the second gap are orthogonally arranged in a non-contact mode. The leakage circular polarization waveguide has the advantage of enhancing the signal coverage intensity and capability.

Description

technical field [0001] The present invention relates to the technical field of communication transmission, in particular to a leaky circularly polarized waveguide. Background technique [0002] In recent years, my country plans to build a new urban rail transit mileage of 35,000 kilometers, including 27,000 kilometers of subway. At the same time, up to now, the operating mileage of urban rail transit in my country has exceeded 6,000 kilometers, of which about 4,500 kilometers are subways. The demand for 5G signal coverage along the rail transit lines is increasing day by day. [0003] The leaky coaxial cable provides a solution to the problem of signal coverage blind spots, but due to the structural limitations of the leaky coaxial cable itself, it is necessary to overcome the disadvantage that the loss increases as the operating frequency increases. The Communication Based Train Control System (CBTC) in the 5.8GHz frequency band needs more efficient and reliable radio wave...
