Blue disk 12 and 14, the setting of 11 rectangular tubulose of waveguide, wherein waveguide 11 include positioned at the installation end face 111 of upper end, peace
Dress is provided with multigroup perforative location hole 112 on end face 111.And the installation end face 111 in the waveguide 11 of rectangular tubular is narrow
The end face on side, two sides are wider broadside end faces, and this case is will to couple output precision to be arranged on the end face of narrow side, then real
Existing narrow side coupling.
With reference to Fig. 3 and Fig. 2, waveguide power divider is combined to be provided with the first deployment line and the second cloth along linear extension direction X
Line is set, the first deployment line is not arranged collinearly with the second deployment line, what multiple coupling output units were arranged along linear extension direction X,
Specifically, coupling output unit 21 is arranged in the first deployment line and is collinearly arranged, and coupling output unit 21 is arranged in
Second deployment line is simultaneously collinearly arranged, this deployment line is virtual for indicating orientation, in actual product and is not present.Positioned at
Coupling output unit 21 in one deployment line is interspersed with the coupling output unit 22 in the second deployment line.And it couples
Output unit 21 is arranged by left side, and coupling output unit 22 is arranged on the right side.
Couple the essentially identical structure of output unit, only probe towards angle, there are different settings, below will be with coupling
Output unit 21 is closed to illustrate.It couples output unit 21 and includes coaxial fitting 212, probe 213 and tuning screw 211, coaxially
Connector 212 is mounted on installation end face 111, and coaxial fitting includes input/output port, inner wire and outer conductor, and inner wire is used for
The effect of linking probe, coaxial fitting is also connection coaxial line, in addition, this case coaxial fitting coaxially connects alternatively at coaxial line
Head is within the scope of the invention with coaxial line.
Coaxial fitting 212 pass through installation end face 111 location hole 112 and stretch to inside waveguide, using be open 121 as
Input terminal, distance is 80mm between the opening 121 and first coaxial fitting 212, and opening 141 is as waveguide pipe end and most
The distance of the latter coupled output is also 80mm.It couples 21 output port 121 of output unit and coupling output unit 22 exports
The half waveguide wavelength for being spaced about corresponding centre frequency of port（λg/2）, also it is smaller than or is more than λ g/2, end
The selection of mouthful spacing determines the working condition of power splitter, and if λ g/2, power splitter works in standing wave state, if being less than or greatly
In λ g/2, then power splitter works in traveling-wave mode.
It is mounted on to 211 screw-thread fit of tuning screw on installation end face 111 and on 212 side of coaxial fitting, tuning
Screw 211 passes through installation end face 111 to stretch to inside waveguide, and tuning screw 211 vertically can carry out position adjusting by X,
Tuning screw 211 is located at the back side of the direction of the parallel portion 215 of probe 213.Also, the position of tuning screw can be figure
Middle position, can also be port offside or other positions, specifically should be premised on it can realize and adjust the degree of coupling, next is examined
Worry facilitates adjusting.
213 L-shaped setting of probe, probe 213 include being parallel to the parallel portion 215 of main mould electric field and perpendicular to main mould electric field
Vertical component effect 214, vertical component effect 214 connect with parallel portion 215, and probe 213 is located in waveguide and is connected to by vertical component effect 214
Coaxial fitting 212, for the parallel portion 215 of probe 213 perpendicular to linear extension direction X, vertical component effect 214 is also perpendicularly to linear extension side
To X and perpendicular to the field distribution of dominant waveguide mode TE10 moulds, parallel portion 215 is parallel to the electric field of TE10 moulds, wherein perpendicular to electricity
The part of field does not couple energy, and induced current will be generated by being parallel to the part of electric field, to which energy to be coupled at output port.
In addition, the degree of coupling of each port can be calculated according to required power-division ratios, so as to by the setting to probe,
Realize corresponding power-division ratios, and outside the present embodiment, the realization method of probe is arbitrary, and can be coaxial type probe,
Can also be the probe that microstrip line is constituted or the probe that co-planar waveguide is constituted.
By two neighboring L-type probe parallel portion towards on the contrary, introducing 180 ° of phases between two neighboring output port
Difference, in addition the space quadrature between two adjacent output ports, it is corresponding with λ g/2 for about 180 ° of space quadrature, reaches output phase
Close to same phase or there is small phase difference, and the phase difference is determined by space quadrature.
With being distributed according to required Taylor's window function, the coupled power amplitude of each output port is calculated, to according to end
Mouth coupled power amplitude is respectively configured each probe, and the length such as the parallel portion of probe is first along linear extension direction successively
It reduces after increase, is determined according to coupled power amplitude needed for calculating, the rule met is that the length of tail portion bending is got over
Long, the electric field strength of position is bigger, then the power magnitude coupled is bigger

Sample is within protection scope of the present invention.
It also should be noted that when waveguide power divider works in traveling-wave mode, an opening is used as input terminal, separately
One opening is used as load end, is non-interchangeable during work, and when waveguide power divider works in standing wave state, two openings
Job specification can be interchanged.
With reference to the input port reflectance factor measured result for the waveguide power divider that Fig. 4, Fig. 4 are design, it is with reference to Fig. 5, Fig. 5
The waveguide power divider of the design amplitude of each output port and phase measured result at 2.8GHz.
Therefore coupled by being open in waveguide narrow side, and can realize multi-path power divider using cascaded structure, reduce work(
Divide body product, passes through the structure for changing probe（The position of bending and the angle of bending）The adjustment for realizing coupling amount, may be implemented
The design of decile and not decile.
By the above method, the distribution that multichannel power is realized in waveguide narrow side is realized in this case, and according to output port
Number only changes the length of power splitter, does not increase the size of power splitter in the other direction, which makes it be suitable for large-scale day
The design of linear array further by reducing duct height, can enable power splitter be stacked up use, to make it
The design requirement that disclosure satisfy that dual-polarized antenna array feeding network, not furthermore with continuously adjustable tuning screw and probe
It, can with setting, it can be achieved that the arbitrary work(of multichannel divides in the power distribution of ratio also, waveguide realizes multi-path power divider using cascaded structure
It is effectively reduced volume.
