Based on the research results of high-temperature superconducting filters in recent years, this paper explores the research process of high-temperature superconducting filters based on quasi-elliptic functions. By using the full-wave filter design method, the coupling between resonators and the structure of the filter In this paper, several kinds of filter designs based on quasi-elliptic functions are simulated and their results are discussed and analyzed.
