摘要：
The judgement of the coupling state of the cavity is the key of the Q-factor measurement in the microwave devices and communication system. A simple and real-time method to determine the coupling state of resonators has been proposed. The coupling states are determined by the graphical relationship between the resonance circles and the match point in Smith chart. The extraction of the coupling coefficient and unloaded quality factor can be performed directly and timely. The procedure is validated with experimental measurements of manufactured cavities. The proposed method could provide an effective way to solve parameters extraction problem for resonators.
