Abstract: This paper presents an innovative miniaturized filtering coupler design methodology. Targeting device miniaturization and reconfigurability, the approach creatively integrates two open-circuited stubs into microstrip coupler branches based on microstrip transmission line theory and low-pass filter prototypes. This achieves functional integration of filtering and coupling capabilities. Both simulation and measurement results demonstrate excellent performance. The proposed method is adaptable to design filtering couplers across various frequencies and dimensions.
