A novel band-pass filter is designed and verified experimentally. The filter consists of five S-shaped slot-line resonators, which are aligned to form an array of coupled slots. The simulated filter pass-band is centered at 1.77 GHz with 0.5% bandwidth and with an exception of small frequency shift (20MHz) shows rather good agreement with measured data. High-temperature superconducting (YBCO) film on 1mm thick LaAIO3 substrate is used to achieve low Insertion loss (-0.6dB at 77K). The filter design is based on the full-wave model of coupled slots, which enables a possibility of quick and accurate circuit simulations using the duality principle.</p
