Abstract:	We report a new type of microstrip bandpass spiral filter structure, which exhibits much smaller size than other existing miniaturized bandpass filter structures, and is particularly useful in developing high-temperature superconducting (HTS) compact filters for cellular communication systems. A prototype three-stage HTS bandpass spiral filter with center frequency of 633 MHz was designed and fabricated on a 20 mm × 8 mm × 0.5 mm LaAlO3 substrate. The measurement results of the spiral filter have good agreements with its electromagnetic full-wave simulation results.
