Abstract
The utility model discloses a structure facilitating to adjust a microwave transmission line standing wave. The structure comprises at least two conductor layers and at least two medium layers arranged at intervals in order from bottom to top. The conductor layers and the medium layers are held in a cavity of the structure. The structure comprises a screw hole arranged at the bottom of the cavity and a screw installed in the screw hole. A through hole corresponding to the screw hole is arranged in the conductor layer and the medium layer closest to the bottom of the cavity. The conductor layer closest to the bottom of the cavity is a grounding wire, and the other conductor layers are microwave transmission lines. The transmission line and a medium are held in the cavity, the distance to the transmission line is adjusted through a screw, and therefore the function of adjusting a transmission line standing wave is achieved. The structure is convenient, does not destroy the transmission structure, does not add components, and ensures stability and reliability of the circuit effectively.
Description
Technical field
The utility model relates to electronic engineering field, particularly relates to being a kind ofly convenient to adjust multiple microwave transmission line and staying wave structure.
Background technology
Current microwave transmission line, for a change its standing wave situation, is generally the physical form that changes transmission line, or increases lumped parameter components and parts.Although these methods can reach the object that standing wave is adjusted, itself or can cause damage to transmission line, or can increase component number, or use the low reliability components and parts such as potentiometer, tunable capacitor, all can make circuit reliability reduce.And when rf frequency is higher, due to circuit tolerance and rigging error, even if designed the welding position of standing wave adjustment components and parts, be also difficult to determine the value of these components and parts when design.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of reasonable in design, simple in structure, cheap, service-strong to be convenient to adjust microwave transmission line and stays wave structure.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind ofly be convenient to adjust microwave transmission line and stay wave structure, comprise spaced at least two-layer conductor layer and at least two layer medium layer successively from bottom to top, conductor layer and dielectric layer are all held to cavity in the inner, be arranged on the screw of cavity bottom, and be arranged on the screw in this screw, wherein, approach most on the conductor layer of cavity bottom and dielectric layer and be equipped with the position through hole corresponding with screw, this conductor layer that approaches cavity bottom is most earth connection, and all the other conductor layers are microwave transmission line.
As a kind of preferred, described dielectric layer is air dielectric.
Further, after described screw adjustment, by glue, fix.
Compared with prior art, the utlity model has following beneficial effect:
The utility model by arranging screw and adjustable screw being installed and being held transmission line and medium on the cavity of ground connection, by screw, regulate the distance between itself and transmission line again, in the situation that not damaging transmission line and not increasing components and parts, the electromagnetic field that changes transmission line distributes, thereby adjust the impedance matching situation of input device and output device, reach the function of improving transmission line standing wave, very convenient, because it does not destroy the structure of transmission line itself, stability and the reliability of circuit have effectively been guaranteed, there is substantive distinguishing features and progress, and the utility model is simple in structure, reasonable in design, cheap, easy to install, there is market application foreground widely, be applicable to applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
1-cavity, 2-screw, 3-screw, 4-through hole, 5-conductor layer, 6-dielectric layer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and execution mode of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, this is convenient to adjust microwave transmission line in wave structure, comprise the conductor layer 5, dielectric layer 6, conductor layer 5, the dielectric layer 6 that are arranged in order from bottom to top, conductor layer and dielectric layer are all held to cavity 1 in the inner, be arranged on the screw 2 of cavity bottom, and be arranged on the screw 3 in this screw, wherein, on above-mentioned undermost conductor layer and dielectric layer, be equipped with the position through hole corresponding with screw 4, thereby above-mentioned screw can turn deeply or exit above-mentioned through hole and screw in screw; This undermost conductor layer is earth connection, and the conductor layer on upper strata is microwave transmission line.As a kind of preferred, above-mentioned dielectric layer can be air dielectric, also can be for meeting other media of microwave transmission requirement.In applying further, on the dielectric layer of the above-mentioned the superiors, can also there be more multi-layered conductor layer and dielectric layer.
During actual use, structure of the present utility model can be applicable to multiple circuit and inputs or outputs on the transmission line of end, microwave signal is transmitted through the transmission line of top conductor layer, the common ground connection of the conductor layer of the bottom and cavity now, and cavity itself can utilize the structure of container that holds circuit devcie.Because the standing wave of its transmission line is not mainly mated and causes by input device resistance and output device, while therefore working, when the standing wave signal on this microwave transmission line need to be adjusted, by turning screw, the distance of adjustment screw and microwave transmission line, can be in the situation that not damaging top conductor layer and not increasing components and parts, and the electromagnetic field that changes transmission line distributes, make the impedance matching situation capable of regulating of input device and output device, thereby reach, adjust the function of improving microwave transmission line standing wave.After adjustment completes, use special-purpose glue to fix screw point glue, make it to be turned again, to guarantee to adjust the stable of rear microwave transmission.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
According to above-described embodiment, just can realize well the utility model.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some that make on the utility model are without substantial change or polishing; the essence of the technical scheme adopting is still consistent with the utility model, also should be in protection range of the present utility model.
