Description
Technical field
The present invention relates to a kind of compact directrix plane return bend.Specifically, relate to by varying width and height
Transmission line section and metallic object load the same phase compact rectangular waveguide or 180 degree of waveguide bends of ridge waveguide constituted.
Background technology
The full bandwidth coupling bending of transmission line is the problem being frequently run onto in modern microwave communication and Military Electronics system.?
Common are 90 degree and one half bend.180 degree of traditional transmission line elbows use the larger radius of curvature smooth and continuous of transmission line
Bending realizes, and volume ratio is bigger.In many situations, such as folded transmission lines time delay line and periodic slow-wave structure
In, the use of multiple above-mentioned elbows, the problem that volume is the biggest is more prominent.On the other hand, 180 degree of traditional E face waveguide bends
The additional difference of shape of 180 degree of phase places can be brought.Different from the difference that electromagnetic wave is produced by certain transmission line, this shape is attached
Adding difference is reversely causing due to transmission line.It is characterized in that this additional difference is unrelated with the overall dimensions size of elbow,
But owing to the input of elbow and the normal direction of outfan cause on the contrary.In folded waveguide travelling-wave amplifier, above-mentioned shape
The additional difference of shape causes the relative bandwidth of operation of such device to be significantly less than whole bandwidth of operation of corresponding rectangular waveguide.
