Description

Ridge waveguide series feed network

Technical field

The invention belongs to microwave technical field, and in particular to a kind of ridge waveguide series feed network.

Background technology

With variation of the electronic systems such as radar, communication to functional requirement, to the demand of antenna just towards multipolarization Direction is developed, and dual polarized antenna can provide abundant target identification performance, strong antijamming capability for electronic system, can meet electricity The multi-functional demand of subsystem and be widely used.At present, the dual polarized antenna for having diversified forms both at home and abroad designs, slotted waveguide Dual polarized antenna is a kind of antenna being adapted in high band operation, and its advantage is that loss is small, reliability is high, available for land, sea The environment such as face, sky, day.

One of difficult point that slotted waveguide dual polarized antenna is realized, it is exactly the feeding classification of dual polarization radiating guide.Quadrature wave It is important feeding classification to lead the coupling series feed mode in gap, for example, what Lv Shanwei was proposed《Orthogonal rectangle waveguide feed gap and spoke Penetrate Coupling Properties of The Slot analysis》In the method for waveguide core slot-coupled mentioned, be exactly this feeding classification canonical form. There is the problem of broadside size is big in rectangular waveguide, be unfavorable for the arrangement and design of dual polarization crack radiating guide.Single ridged waveguides has There is the advantages of broadside size is small, beneficial to the arrangement of variety classes gap radiation waveguide, so being set in slotted waveguide dual polarized antenna It is widely adopted in meter.So using rectangular waveguide to the feeding classification of ridge waveguide, the broadside size of radiating guide can be reduced, The spacing reduced between radiating guide, beneficial to the realization of Waveguide slot dual polarized antenna.

The content of the invention

It is an object of the invention to provide a kind of compact-sized ridge waveguide series feed network.

To achieve the above object, the invention provides following technical scheme：A kind of ridge waveguide series feed network, including it is more Individual ridge waveguide and a rectangular waveguide, there is a common wall between each ridge waveguide and rectangular waveguide, the common wall, which is provided with, to be used for Connect the gap of ridge waveguide and rectangular waveguide power splitter branch-waveguide pipe.

The gap substantially S types, specifically include the vertical masonry joint part at middle part and the bent portion at both ends；Wherein vertical masonry joint part Length direction relative to ridge waveguide and rectangular waveguide is angularly disposed.

Each ridge waveguide is parallel to each other, and each ridge waveguide is mutually perpendicular to rectangular waveguide or orthogonal setting.

The rectangular waveguide is a rectangular waveguide power splitter, the waveguide of each ridge waveguide and the rectangular waveguide power splitter Branch connects.

The incline direction of the vertical masonry joint part in two gaps between adjacent two ridge waveguides and rectangular waveguide is opposite.

Convex ridge in the ridge waveguide is located remotely from the inwall of common wall side.

The technical effects of the invention are that：The rectangular waveguide of branch path is replaced using ridge waveguide, is come by using S types gap Realize electromagnetic coupled of the rectangular waveguide to ridge waveguide.This method have compressed the waveguide broadside size being fed, and solve rectangle The problem of waveguide is to ridge waveguide series feed.
