Abstract
The utility model relates to a novel air cavity bridge for microwave communication. A main line conduction band and a subline conduction band are not in the same horizontal plane and are placed in a cavity body; and coupled areas of both the main line conduction band and the subline conduction band are mutually overlapped. The provided novel air cavity bridge has the advantages of less influence to discontinuity, achievement of input and output on the same side and simple processing process.
Description
Technical field
The utility model relates to employed electric bridge in the microwave technical field such as communication, radar, especially refers to the directed air cavity of a kind of wideband electric bridge.
Background technology
Electric bridge is used for microwave signal and distributes by special ratios or synthesize power, is one of element the most frequently used in the microwave technical field, generally fills strip line electric bridge and air chamber strip line electric bridge based on medium.In order to realize the application of broadband or ultra-wideband communications, existing electric bridge is many to be occurred with multistage parallel coupled line cascade system.Conduction band thickness in its medium filling tape shape line electric bridge is about 0.03mm, the dielectric constant of medium is 2.5～4.3, the coupling line gap is very little, can limit it greatly bears power so on the one hand, can increase straight-through loss greatly on the other hand, so be not suitable for being applied to high-power low-loss occasion; And be to obtain the bigger power that bears in the existing air chamber strip line electric bridge, adopt thicker conduction band, when multi-stage cascade is used, because the transmission line discontinuity that the saltus step of transmission line size brings influence becomes especially outstanding.Therefore the strip line electric bridge of medium filling has the defective of Power Limitation.The air chamber strip line is because the restriction of structure, causes two inputs of electric bridge and the output can not be in the same side of cavity, the unnecessary trouble that has caused this device to bring in installation process.
The utility model content
The utility model is at the deficiencies in the prior art, and it is more little to have designed and developed out a kind of discontinuity influence, realizes that input and output pass in and out the simple novel air cavity of processing technology electric bridge with the limit.
The utility model is achieved through the following technical solutions:
A kind of novel air cavity bridge that is used for microwave communication includes cavity, is provided with main line conduction band and by-pass conduction band in the cavity, and described main line conduction band and by-pass conduction band are not placed in the cavity on same horizontal plane.
A kind of novel air cavity bridge that is used for microwave communication, described main line conduction band and the by-pass conduction band that is placed in the cavity has difference in height.
A kind of novel air cavity bridge that is used for microwave communication, the coupled zone of described main line conduction band and by-pass conduction band is overlapped.
A kind of novel air cavity bridge that is used for microwave communication, described main line conduction band and by-pass conduction band are overlapped in the close coupling district.
The zone of main line conduction band and the coupling of by-pass conduction band is the coupled zone.Main line and by-pass are about coupled zone, cavity center symmetry.But main line conduction band and by-pass conduction band are not horizontal parallel in cavity, and distance is up and down arranged between the two.Wherein main line conduction band and by-pass conduction band partly are overlapping up and down in close coupling, and try to achieve by calculating in gap between the two.The main line conduction band partly is parallel with the by-pass conduction band in loose coupling, but not at grade.Just because of this cross structure, can realize that the input of device and output are at grade.Changed in the traditional design, two leads of traditional electric bridge cause the input of electric bridge and output not in the same side at grade.The utility model adopts staggered conduction band, thus the input of electric bridge and output structural limitations at grade.That can install on the engineering is convenient.And this structure can reduce the discontinuity of electric bridge.
