Cable is leaked in a kind of MIMO waveguidesTechnical field
The present invention relates to one kind to leak cable, particularly a kind of MIMO waveguides leakage cable.
Background technology
With requirement more and more higher of the communication system to message transmission rate, MIMO technology is widely used.In order to meetThe use of the confined spaces such as tunnel, MIMO rectangular waveguides increasingly attract attention.The technology is by the way that two rectangular waveguides are closedTogether, and different gaps is opened in two waveguides, realizes horizontal polarization and vertical polarization respectively, forms MIMO.But the rectangular waveguideInstall and safeguard and be relatively difficult.And MIMO rectangular waveguides are to merge two rectangular waveguides, considerably increase its chiVery little and cost.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of MIMO waveguides leakage cable, and cost simple in construction is relatively low.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
Cable is leaked in a kind of MIMO waveguides, it is characterised in that：It is set in comprising a waveguide and oversheath, oversheath outside waveguideSide, a metal partion (metp) is provided with waveguide, metal partion (metp) is set along guide length direction and metal partion (metp) both sides are fixedWaveguide is divided into first wave guide and second waveguide on waveguide inside pipe wall, is equidistantly provided with the waveguide of first wave guideOne radius, the second radius, the polarization of the first radius and the second radius are equidistantly provided with the waveguide of second waveguideDirection is different.
Further, the waveguide is the waveguide that section is ellipse, and metal partion (metp) is arranged on transverse.
Further, the waveguide is that section is circular waveguide, and metal partion (metp) is arranged on circular waveguide oneOn radial line.
Further, first radius is axially arranged along waveguide, and the second radius is set perpendicular to the first radiusPut.
Further, first radius is axially arranged along waveguide, and the second radius favours the first radius and setPut.
Further, the waveguide is arranged to wrinkle shape embossing or spiral shape embossing.
The present invention compared with prior art, has advantages below and effect：The present invention in a waveguide between plus metal everyPlate, it neither influences the transmission performance of waveguide, and and can increases a transmission channel, greatly in the case where not increasing waveguide dimensionsCost is reduced greatly, while two kinds of different radius are driven in two and half waveguides, produces different polarised directions, forms MIMO,Compared with MIMO rectangular waveguides, wrinkle can be processed into by embossing technique or spiral shape embossing can be more easy into diskIn transport, installation and safeguard.

Embodiment
Below in conjunction with the accompanying drawings and the present invention is described in further detail by embodiment, and following examples are to this hairBright explanation and the invention is not limited in following examples.
Embodiment 1：
As depicted in figs. 1 and 2, a kind of MIMO waveguides leakage cable, comprising a waveguide 1 and oversheath 7, oversheath set 7 is located at rippleThe outside of conduit 1, is provided with a metal partion (metp) 2 in waveguide 1, metal partion (metp) 2 set along the length direction of waveguide 1 and metal everyThe both sides of plate 2 are fixed on the inwall of waveguide 1 is divided into first wave guide 3 and second waveguide 4, the waveguide of first wave guide 3 by waveguide 1The first radius 5 is equidistantly provided with pipe, the second radius 6, the first radius are equidistantly provided with the waveguide of second waveguide 45 is different with the polarised direction of the second radius 6.
Waveguide 1 is the waveguide that section is ellipse, and metal partion (metp) 2 is arranged on transverse.The edge of first radius 5Waveguide is axially arranged, and the second radius 6 is set perpendicular to the first radius 5.Waveguide 1 is arranged to wrinkle shape embossing or spiralShape embossing, can be into disk, it is easier to transport, install and safeguard.
Embodiment 2：
As shown in figures 1 and 3, a kind of MIMO waveguides leakage cable, comprising a waveguide 1 and oversheath 7, oversheath set 7 is located at rippleThe outside of conduit 1, is provided with a metal partion (metp) 2 in waveguide 1, metal partion (metp) 2 set along the length direction of waveguide 1 and metal everyThe both sides of plate 2 are fixed on the inwall of waveguide 1 is divided into first wave guide 3 and second waveguide 4, the waveguide of first wave guide 3 by waveguide 1The first radius 5 is equidistantly provided with pipe, the second radius 6, the first radius are equidistantly provided with the waveguide of second waveguide 45 is different with the polarised direction of the second radius 6.
Waveguide 1 is that section is circular waveguide, and metal partion (metp) 2 is arranged on 1 one radial lines of circular waveguide.FirstRadius 5 is axially arranged along waveguide, and the second radius 6 favours the setting of the first radius.Second radius, 6 adjacent two spokesGroove is penetrated to set in splayed.Waveguide 1 is arranged to wrinkle shape embossing or spiral shape embossing, can be into disk, it is easier to transport,Installation and maintenance.
The present invention in a waveguide between plus metal partion (metp), it neither influences the transmission performance of waveguide, and and can is not increasingIn the case of waveguide dimensions, increase a transmission channel, substantially reduce cost, at the same open in two and half waveguides two kinds it is differentRadius, different polarised directions is produced, form MIMO, compared with MIMO rectangular waveguides, can be processed into by embossing techniqueWrinkle or spiral shape embossing enable its its into disk, it is easier to transport, install and safeguard.The present invention can also be by two solelyVertical waveguide carries out extruding and is merged into similar structures in embodiment, i.e., is not other dividing plate, but obtained by crimpSimilar structures.Groove profile designed by the present invention is not limited to above case, and polarization mode is not limited to not same polarization or identicalPolarization.
