Description
Technical field
The present invention relates to be a kind of microwave circuit that can make with co-planar waveguide and the microwave circuit made from microstrip line is integrated in integrated co-planar waveguide/microstrip transitions connector on the same medium substrate effectively, this connector can be used for microwave circuit and the microwave integrated circuit in the various electronic equipments, its use helps the integrated and miniaturization of circuit, belongs to microwave technical field.
Background technology
Conversion connector between the different microwave transmission structures is a kind of microwave component commonly used, as coaxial/microstrip transitions joint, coaxial/waveguide transitions joint promptly is two kinds of modal conversion connectors, because application is very extensive, these two kinds of conversion connectors have become the standard component as plug, socket in working in the electronic equipment of microwave band.Coaxial/microstrip transitions joint meaning can realize by coaxial line to microstrip line or by microstrip line to a kind of joint of changing the coaxial line, coaxial/waveguide transitions joint meaning can realize by coaxial line to waveguide or by waveguide to a kind of joint of changing the coaxial line, similar co-planar waveguide/microstrip transitions connector then be a kind of realize by co-planar waveguide (Fig. 1 .a) to microstrip line (Fig. 1 .b) or by microstrip line to the joint of changing the co-planar waveguide.What co-planar waveguide/microstrip transitions connector commonly used at present adopted is a kind of gradual transition structure.The structure of the structure of co-planar waveguide and microstrip line has bigger difference as shown in Figure 1, the center conduction band of co-planar waveguide and metal base plate are made in the same one side of medium substrate, the conduction band of microstrip line and metal base plate then are in the two sides of medium substrate respectively, because the way of being accustomed in the low-frequency channel that directly metal base plate of the metal base plate of microstrip line and co-planar waveguide is coupled together with lead can't guarantee effective transmission of frequency electromagnetic waves, therefore, for the connection between these the two kinds of transmission structure metal base plates of transmission characteristic that obtain need be through the transition of a segment distance, just need the gradual change of longer distance and can not suddenly change, promptly make metal base plate move on to another side by the one side of medium substrate by gradual change.But it is big that the problem that grading structure brings is a size, is unfavorable for the miniaturization of microwave circuit.In the practical application when needs mix to use co-planar waveguide and microstrip line, circuit designer usually with the design of different transmission structures on two different medium substrates avoiding on same medium substrate, carrying out the conversion of co-planar waveguide and microstrip line, but so again to the integrated difficulty of having brought of microwave circuit.
Invention meat holds
The objective of the invention is to problem at above-mentioned existence, propose a kind of integrated little band/co-planar waveguide conversion connector of novel structure, it can be integrated on the same medium substrate effectively with co-planar waveguide microwave circuit of making and the microwave circuit made from microstrip line.Technical solution of the present invention: its structure is the same one side that the metal base plate of the metal base plate of microstrip line and co-planar waveguide is in medium substrate, the center conduction band of the conduction band of microstrip line and co-planar waveguide passes medium substrate and links together, be spaced apart the 0.4-0.8 millimeter between the center conduction band of co-planar waveguide and the metal base plate, the junction of co-planar waveguide and microstrip line is designed to 120～150 ° oblique angle.Advantage of the present invention: simple in structure, size is little, be easy to make.

Fig. 1 .b is a microstrip line.
Accompanying drawing 2 is structural representations of the present utility model.
Accompanying drawing 3 is the integrated co-planar waveguide/transmission characteristic of microstrip transitions connector and the schematic diagram of reflection characteristic.
Among the figure 1 is metal base plate, the 2nd, the center conduction band, the 3rd of co-planar waveguide, the conduction band of microstrip line, the 4th, medium substrate.
Embodiment
Embodiment 1 (contrast accompanying drawing 2), the metal base plate 1 of microstrip line and the metal base plate 1 of co-planar waveguide are in the same one side of medium substrate 4, and the conduction band 3 of microstrip line passes medium substrate 4 with the center conduction band 2 of co-planar waveguide and links together.For getting 0.4 millimeter of size in the center conduction band and the interval between the metal base plate of the loss junction co-planar waveguide that reduces connector, need be designed to 120 ° oblique angle simultaneously for the junction of the reflection characteristic co-planar waveguide that improves joint and microstrip line.
Integrated co-planar waveguide/microstrip transitions connector simple in structure, size is little,, be easy to make.Adopt this transformational structure will help the integrated and miniaturization of microwave circuit.Therefore, the present invention should have application prospects.
