Abstract
The utility model relates to a conduction band of a strip line directional coupler. The conduction band comprises a conduction band body placed inside the cavity of the coupler, the conduction band body comprises a main line conduction band body and an auxiliary conduction band body, and a projection is arranged on at least one side of the main line conduction band body and/or the auxiliary conduction band body. The utility model provides a strip line directional coupler having the benefits of 10 times or more bandwidth scalability, better directionality under smaller discontinuity, and easy process procedure.
Description
Technical field
The utility model relates to the coupler of communication, radar, relates in particular to a kind of conduction band structure of directed cavity coupler.
Background technology
In existing air chamber strip line coupler in coupling regime, main line conduction band and by-pass conduction band are in full accord in size saltus step place, Gu the time power transformation DISTRIBUTION OF MAGNETIC FIELD that encourages in the time of guaranteeing to transmit microwave signal by two conduction bands also is on all four, thereby the discontinuity unanimity of two conduction bands.Main line conduction band and by-pass conduction band are in full accord in size saltus step place, and the by-pass conduction band need not carry out large-scale size when saltus step crosses over, and reduces discontinuity.Though the main line conduction band increases to some extent in the discontinuity of saltus step place, because symmetrical configuration, the amplitude of increase is very little, can ignore.But in the course of processing of reality, because the deviation of machining accuracy can cause the electric index of device can not satisfy basic demand, the actual index and the result of desirable emulation have very big difference, and be excessive such as standing-wave ratio, directivity is relatively poor, the degree of coupling off-center degree of coupling.
The utility model content
The utility model provides a kind of frequency range can realize 10 times or higher sound interval at the deficiencies in the prior art, and the discontinuity influence is more little, and directivity is better, the simple strip line directional coupler of processing technology.
The utility model is achieved through the following technical solutions:
A kind of conduction band of strip line directional coupler comprises the conduction band body that is placed in the coupler cavity, and described conduction band body side is provided with at least one projection.
A kind of conduction band of strip line directional coupler, described conduction band body comprise main line conduction band body and by-pass conduction band body, and projection is arranged at least one side of main line conduction band body or by-pass conduction band body or main line conduction band body and by-pass conduction band body body.
A kind of conduction band of strip line directional coupler, described projection are cuboid or spherical surface body or polygon cube.
The utility model adds projection by the side at conduction band, and the effectively electric index of trim, and the position difference of placing can be brought different effects, so the index that can reach is according to actual needs regulated the position and the size of projection.Through evidence, conduction band one can be realized 10 times or higher sound interval after being sidelong and putting projection, and the discontinuity influence is more little, and directivity is better, and processing technology is simple.

Embodiment
Embodiment 1
Shown in accompanying drawing.
Be provided with main line conduction band body 1 and by-pass conduction band body 2 in the cavity 3, projection 4 is separately positioned on a side of main line conduction band body 1 and by-pass conduction band body 2.The projection 4 of main line conduction band body 1 one sides is a cuboid, and the projection 4 of a side of by-pass conduction band body 2 is a spherical surface body.The electric index that adds projection 4 back directional couplers obviously will be got well than the index of conventional band line directional coupler.And the position difference of placing can be brought different effects, so the index that can reach is according to actual needs regulated the position and the size of projection 4.
