Abstract
The invention discloses a multi-path unequally-divided radial waveguide power divider. The multi-path unequally-divided radial waveguide power divider comprises a hollow waveguide circular disc, wherein an input end stepped impedance transformer is arranged on a middle point on one surface of the waveguide circular disc while a plurality of annular regions, concentric with the waveguide circular disc, are on the other surface of the waveguide circular disc; a plurality of output end stepped impedance transformers are uniformly distributed on each annular region; the input end stepped impedance transformer is connected with coaxial line feed input which generates an electric field and a magnetic field; and the electric field is parallel to the axial line of the waveguide circular disc while the magnetic field direction rotates around a circumferential direction. Based on the coaxial symmetry characteristic of the radial waveguide main mode field distribution, power division of different proportions is realized on circles with different radiuses r by taking the input port as the center, through corresponding output ports; in addition, the number of the power division paths is flexible, and multi-path and multi-proportion division can be realized; and therefore, the multi-path unequally-divided radial waveguide power divider can be widely applied to various radar systems and communication systems with amplitude modulation requirements on an antenna array.
Description
Technical field
The present invention relates to a kind of power splitter, more particularly, to a kind of multichannel not decile radial waveguide power divider.
Background technology
Power divider is the important basic device of a class in microwave engineering, and it is widely used in civil telecommunications, micro-
In the various civilian, military equipment such as wave measurement, radar, communication, electronic countermeasure, Aero-Space, primarily serve in a device to biography
Microwave energy on defeated path is accurately distributed by system requirements to the effect of antenna end, joins with power combiner and microwave amplifier

Two-way power divider.
Traditional its technical problem of binary power allotter and defect are mainly reflected in following two aspects：
1., because Wilkinson power division network adopts microstrip line or strip line as the carrying transmission line of circuit, realize when needing device
Vast scale does not wait timesharing, and Xu Jiang mono- road multi-branch transport line impedence is designed to very high, but it is various to be limited to processing technique, reliability etc.
Factor affects, and such circuit enables not decile ratio and can reach 3：1 belongs to and being difficult, and needs with the technology of amplitude weighting aerial array
Ask and compare also quite gap.
2., for the T junction structure power divider of conventional waveguide type, multichannel distribution need to be realized by way of cascade,
Lead to multichannel distribution network volume excessive.And this class formation is difficult to realize the power distribution on odd number road.
Content of the invention
The purpose of the present invention is that offer one kind solves the above problems, and improves power divider not decile ability, simultaneously
Make work(branch number more flexible, be no longer limited by 2nRelation, reduces device loss, the multichannel of boost device power bearing ability is not
Decile radial waveguide power divider.
To achieve these goals, the technical solution used in the present invention is such：A kind of multichannel not decile radial waveguide
Power divider, including a hollow waveguide disk, described waveguide disk one side midpoint is provided with input stepped impedance transformer,
Another side includes several annuluses concentric with waveguide disk, and each annulus is evenly distributed with several outfan stepped impedances
Changer,
Described input stepped impedance transformer, outfan stepped impedance transformer are all vertical with the surface of place waveguide disk,
And constituted by changer body and probe, changer body is located inside waveguide disk, and probe passes corresponding waveguide disk table
Face；
The probe of described input stepped impedance transformer is used for the coaxial feeding input in raw electric field and magnetic field of practicing midwifery, described electricity
With the diameter parallel of waveguide disk, circumferentially direction rotates magnetic direction.
As preferred：Annuluses are 2, and on the annuluses of waveguide disc centre, outfan stepped impedance transformer is
Four, on annuluses on another annuluses, outfan stepped impedance transformer is eight.
Compared with prior art, it is an advantage of the current invention that：Due to being inputted using coaxial feeding, connect defeated after coaxial line
Enter to hold stepped impedance transformer to be transitioned into waveguide disk, the electric field of waveguide disk is perpendicularly oriented to another side, magnetic field from disk one side
Circumferentially direction rotates in direction, and its field distribution is symmetrical, and the outfan stepped impedance being inserted in same Radius annuluses becomes
Parallel operation probe is circumferentially symmetrical, and the amplitude of such power distribution and phase place have good concordance.
The probe of the outfan stepped impedance transformer of different annuluses is circumferentially symmetrical in different radiuses, due to
There is different radii annuluses, and we are distinguished with large radius ring, minor radius ring, then the outfan stepped impedance on minor radius ring becomes
The output of parallel operation is strong, and the output of large radius ring is relatively weak, and degree of strength is related to the distance at center to it.And ring
The quantity in shape area is related to wanting the distribution realizing how many roads.Different proportion difference way can be realized in so different annuluses
Not decile distribution, this way is not limited to 2n.And the transmission path due to waveguide type, compared to traditional Wilkinson power
Allotter has lower loss and bears bigger power capacity.
Method for designing of the present invention and traditional power divider have difference substantially, and the present invention utilizes radial waveguide master
Mode distributions have the characteristics that coaxial-symmetrical, by output port on the circle of the different radii r with input port as the center of circle
To realize the power distribution of different proportion, and work(branch number is flexibly, achievable multichannel, the distribution of multiple ratio, by this invention institute
The power divider of design have enable multiple pro rate ratios, work(branch number flexibly, that loss is low, power capacity is big etc. is excellent
Gesture.Power divider design method proposed by the invention, the different ways of realization of energy more convenient and quicker, the big work(of different proportion
Rate power distribution.And more preferable amplitude coincidence and phase equalization can be realized in each road of decile.
