Abstract—A study of the current–voltage characteristics of structured high-temperature superconducting (HTSC) films based on YBa2Cu3O7 – x–YBa2Cu3O7 – x showed that the critical current of the film structure with an area of 10.0 × 10.0 mm2 can be reduced from 10 A up to 100 mA. By the example of an HTSC resonator, it is shown that in the millimeter wavelength range, with a resonance response width of 2∆f = 20–30 MHz at a level of 0.5 of its amplitude, a structured film used as an “grounded” plane permits tuning of the resonator in a band of at least 300 MHz.
