Abstract

The invention discloses a MIMO waveguide leaky cable comprising a waveguide tube and an outer sheath which sleeves the waveguide tube. The waveguide tube is internally provided with a metal baffle plate which is arranged along the length direction of the waveguide tube, and two sides of the metal baffle plate are fixed to an inner wall of the waveguide tube to divide the waveguide tube into a first waveguide and a second waveguide. First radiation slots are arranged on a waveguide tube of the first waveguide with equal intervals, second radiation slots are arranged on a waveguide tube of the second waveguide with equal intervals, and the first radiation slot and the second radiation slot have different polarization directions. According to the MIMO waveguide leaky cable, the metal baffle plate is added to one waveguide, the transmission performance of the waveguide is not affected, a transmission channel can be added in the condition of not increasing the size of the waveguide, the cost is greatly reduced, at the same time, two kinds of different radiation slots are opened on two half waveguides, different polarization directions are generated, an MIMO is formed, compared with a MIMO rectangular waveguide, the MIMO waveguide leaky cable can be formed into discs and is easier to transport, install and maintain.

Description

technical field [0001] The invention relates to a leaky cable, in particular to a MIMO waveguide leaky cable. Background technique [0002] As communication systems have higher and higher requirements on data transmission rates, MIMO technology is widely used. In order to meet the use of confined spaces such as tunnels, MIMO rectangular waveguides have attracted more and more attention. This technology forms MIMO by combining two rectangular waveguides and opening different gaps between the two waveguides to achieve horizontal polarization and vertical polarization respectively. But the rectangular waveguide is difficult to install and maintain. And the MIMO rectangular waveguide combines two rectangular waveguides, which greatly increases its size and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a MIMO waveguide leaky cable with simple structure and low cost. [0004] In order to solve the problems ...
