Recently, we have succeeded in fabricating HTS ring resonators by using the double-side YBCO films deposited on LaAlO3 (LAO) substrates. Quality factor (Q) over 104 at 5 K with resonating frequency of 3.61 GHz has been demonstrated. Furthermore, by creating a narrow gap in the same ring structure, we found that the resonating frequency splits into two, one occurred at half and three halves of the original one (i.e. at 1.80 GHz and 5.33 GHz, respectively). The temperature dependence of the resonating frequency and Q-value were studied in detail. We found that although the resonating frequency changes by introducing the gap, the Q-value remains essentially unchanged.
