摘要
A strip loop resonator, comprising: a loop-shaped strip line (187, 193, 214, 225, 235) for resonating a microwave in a single mode according to a line impedance thereof; an input strip line (185) for inputting the microwave to an input point of the loop-shaped strip line in electromagnetic coupling; and an output strip line (186) for outputting the microwave resonated in the loop-shaped strip line from an output point of the loop-shaped strip line in electromagnetic coupling,characterized in that the loop-shaped strip line has an electric length shorter than a wavelength of the microwave and comprises: a pair of coupling partial lines (182a; 182b, 192a; 192b, 222a; 222b, 232a; 232b) arranged in parallel to each other to couple the coupling partial lines to each other in electromagnetic coupling, the line impedance of the loop-shaped strip line being dependent on the electromagnetic coupling between the coupling partial lines; a first side strip line of which both ends are connected to first side ends of the coupling partial lines, the input point of the loop-shaped strip line being placed at the first side strip line; and a second side strip line of which both ends are connected to second side ends of the coupling partial lines, the output point of the loop-shaped strip line being placed at the second side strip line, and the output point of the loop-shaped strip line being spaced a half wavelength of the microwave apart from the input point of the loop-shaped strip line.
