概要

In this study, four types of miniaturized high-temperature superconductor (HTS) filters are developed by using coplanar waveguide (CPW) quarter-wavelength resonators. The filters have greatly reduced size compared with most previous CPW　HTS filters. They are designed by employing an electromagnetic simulator in combination with appropriately chosen equivalent circuits, and are fabricated using YBCO films deposited on MgO substrates. Their measured frequency responses agree well with theoretical predictions, and show low insertion losses in spite of their small sizes.
