Abstract
The utility model relates to a conduction band of a cavity coupler, which comprises a main band and an auxiliary band. When the main band and the auxiliary band are positioned inside a cavity, the shapes of the main band and the auxiliary band are asymmetric in the coupling area of the main band and the auxiliary band. Guide angles of 45DEG are formed at the corners of the two ends of the auxiliary band. In the conduction band provided in the utility model, the shape of the main band and the auxiliary band in the coupling area inside the cavity are asymmetric, so as to increase the distance between the main band and the auxiliary band, thereby well controlling the coupling degree between the main band and the auxiliary band. In addition, the guide angles formed at the corners of the two ends of the auxiliary band can further improve the coupling effect between the main band and the auxiliary band.
Description
Technical field
The utility model relates to a kind of coupler that is used for communications, is specifically related to a kind of conduction band structure of cavity coupler.
Background technology
Cavity coupler is used for communication signal transmission at present in a large number, but the master tape of cavity coupler and subband partial shape of coupled zone in cavity are symmetry at present, distance between master tape and the subband is more approaching, like this can not the better controlled master tape and subband between the degree of coupling, make that the whole coupling effect of cavity coupler is undesirable.
The utility model content
The utility model has been designed and developed out the cavity coupler conduction band of the degree of coupling between a kind of energy better controlled master tape and the subband at the deficiencies in the prior art.
The utility model is achieved through the following technical solutions:
A kind of conduction band of cavity coupler includes master tape and subband, and when described master tape and subband were placed on cavity, in master tape and subband coupling regime, master tape and subband shape were asymmetric.
A kind of conduction band of cavity coupler has lead angle on the turning of described subband termination.
A kind of conduction band of cavity coupler all has lead angle on the turning of described subband two ends.
A kind of conduction band of cavity coupler, the lead angle on the turning, described subband termination are 20 °～80 °.
A kind of conduction band of cavity coupler, the lead angle on the turning, described subband termination is 45 °.
Being shaped as of the utility model master tape and the subband coupled zone in cavity is asymmetrical, has increased the spacing between master tape and the subband like this, the degree of coupling between energy better controlled master tape and the subband.Lead angle is all arranged on the turning of subband two ends, can further improve the coupling effect between master tape and the subband like this.
Description of drawings
Accompanying drawing is a structural representation.
Embodiment
Embodiment 1
Shown in accompanying drawing.
The utility model includes master tape 1 and subband 2, and when master tape 1 was placed on cavity 3 with subband 2, in master tape 1 and subband 2 coupling regimes, master tape 1 and subband 2 shapes were asymmetric.Increased the spacing between master tape 1 and the subband 2 like this, the degree of coupling between energy better controlled master tape 1 and the subband 2.
Embodiment 2
Shown in accompanying drawing.
The utility model includes master tape 1 and subband 2, and when master tape 1 was placed on cavity 3 with subband 2, in master tape 1 and subband 2 coupling regimes, master tape 1 and subband 2 shapes were asymmetric.Increased the spacing between master tape 1 and the subband 2 like this, the degree of coupling between energy better controlled master tape 1 and the subband 2.On the turning of subband 2 one terminations lead angle is arranged, lead angle is 45 °.Lead angle on the turning, subband 2 termination can further improve the coupling effect between master tape 1 and the subband 2.
