The end of ring will have with outer conductor good to be contacted or is directly welded on outer conductor.There are following for the mode of this loop coupling
Problem, first, we design process ring when it is difficult to ensure that ring shape and emulation when reach consistent, can only basis
Actual shape carries out the coupling of debugging resonant cavity；Second, the weld of coupling ring can be deformed upon with the growth of time, this
It can influence the excitation and coupling of resonant cavity.The microstrip coupled ring of resonant cavity of the present invention can determine coupling by the debugging of simulation stage
The shape size of cyclization ensure that the stability and one of coupling ring performance then by being machined the coupling ring to suit the requirements
Cause property, meanwhile, this resonant cavity coupling ring accurately processed can be subjected to the test of time, reliable and stable when long.
