Abstract
Two conducting lines are arranged in a ring form in a TEM-mode transmission line. The end of one of the lines is connected to the end of the other line with opposite polarity, thus forming a resonator for resonation in a half-wavelength mode. This structure, free of line discontinuity which lowers the Q value, can provide a resonator having a high Q value equivalent to that of the one-wavelength resonator. Moreover, it is satisfactory to provide a half of a length of the one-wavelength resonator. Accordingly, the structure of the resonator has reduced size but little Q-value deterioration.
