Description
Technical field
The invention belongs to electronic communication technology fields, are filled more particularly to a kind of waveguide coaxial connecter exported from narrow side
It sets.
Background technology
Waveguide coaxial connecter device is radar system devices, navigation system devices, microwave telecommunication devices and microwave test system
An extremely important passive device in system.For electromagnetic wave signal in waveguide to be converted in coaxial or microstrip transmission line,
Subsequent signal processing is carried out convenient for system.
The design requirement of waveguide coaxial connecter device：Insertion Loss is small, and standing wave is low, with roomy, small.Current most common square
There are two types of shape waveguide coaxial connecter devices, and one is most common orthogonal modes waveguide coaxial connecter device, the waves of this kind of form
Lead the broadside that coaxial conversion equipment coaxial output line mouth is located at waveguide；It is for second the waveguide coaxial connecter device of termination form,
This kind of form coaxial port is exported by the terminal area of rectangular waveguide.
In microwave electron system, due to requiring system structure layout and system compact, generally require straight
It connects from the narrow side of waveguide and is coupled out electromagnetic wave signal, so that system carries out signal processing.In this case, above two waveguide
Coaxial conversion cannot be all directly realized by from the narrow side of waveguide and be exported due to the inherent shortcoming of its structure, it is necessary to coordinate waveguide or
The a series of turning structure of cable could be realized.Thus, inherently volume and weight be brought to increase, it is unfavorable for total system
The small form factor requirements of system, cost increase, while increasing complete machine complexity, deteriorating system performance.
Invention content
Present invention aims at the defect for existing waveguide coaxial connecter device, provide it is a kind of can be directly from waveguide
The waveguide coaxial connecter device of narrow side output.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of waveguide coaxial connecter device exported from narrow side, including rectangular waveguide and coaxial port, it is characterised in that：Institute
State the narrow side that coaxial port is located at the rectangular waveguide；With the opposite rectangular waveguide of narrow side where the coaxial port another
There are one steps for one jiao of setting of narrow side；It is provided with the boss with multiple steps in the rectangular waveguide cavity, the multiple
Rank is increased successively, and lowest-order step is right against the direction of waveguide mouth, remaining step turns round the square for turning 90 degrees the output of face coaxial port
The narrow side direction of shape waveguide, the coaxial port are located at highest stage rank.
Preferably：There are three steps for the boss tool.
A gap is opened at the top of the highest stage rank, the welding for coaxial connector inner core positions.
It is further characterized by：The number of steps of the boss requires synchronous increase with according to bandwidth of operation.
The coaxial port of waveguide coaxial connecter device of the present invention is mounted in the narrow side of rectangular waveguide, close in rectangular waveguide
A boss structure with turning is designed in endface, and the inner core of coaxial connector is directly welded at boss top, realizes waveguide
To coaxial conversion function.The waveguide coaxial connecter device of the form equally has a very wide relative bandwidth, lower standing wave and
The Insertion Loss of very little.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the simulation curve figure of waveguide coaxial connecter device.
Specific implementation mode
Fig. 1 is the interior three-dimensional figure of the coaxial conversion equipment of novel waveguide, includes the port of rectangular waveguide 1；2 be 50 ohm
Coaxial port 2（The port can also be microstrip line port as needed）；In the cutting on one side far from coaxial port 2 of rectangular waveguide 1
A step 3 is opened, returning for entire waveguide coaxial connecter device can be improved by controlling the size of the length of the step 3 and wide both direction
Wave.One boss 4 is set in the cavity of rectangular waveguide, and the boss 4 has multi-stage stairs, and the number of step is by needing work
Bandwidth determine, bandwidth requirement is wider, then step number requires more.Boss 4 includes three steps in the present embodiment, wherein
First order step is minimum, and afterbody step highest, intermediate step increases successively.There are one 90 degree of turns among the boss 4
Kinking structure, first order step is right against the port direction of rectangular waveguide 1, and back two-stage step is then turned round and turn 90 degrees face needs together
The narrow side direction of shaft end mouthful output.A gap 5 is opened at the top of afterbody step, is the weld part of 2 inner core of coaxial port
Position, positioning when for welding coaxial connector inner core, the inner core of coaxial port being placed in the gap, is then welded.It should be due to
The gap is designed, welding positioning is extremely convenient, is easy location control location tolerance.Distance 6 He of the boss to Waveguide end face
Boss controls the distance at two and similarly helps to improve entire Waveguide coaxial to the distance 7 of 2 place narrow side end face of coaxial port
The echo of conversion equipment.
Fig. 2 is the simulation curve figure of the waveguide coaxial connecter device, by simulation curve figure it is found that the waveguide of the structure is same
Shaft rotation changing device has very excellent performance.
The above be that a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
The specific implementation of the present invention is confined to these explanations.For any people for being familiar with this technology and its field, this hair is not being departed from
Under the premise of bright design, various deductions or change may be made, the protection domain of the utility model should be all belonged to.
