CROSS-COUPLED ELLIPTIC FUNCTION BANDPASS FILTERS AND NOVEL MICROSTRIP EDGE-COUPLED SPLIT RING RESONATORS

摘要

A micro-strip ring resonator is provided to improve a coupling efficiency by increasing capacitance and equivalent capacitance, thereby enhancing the quality of the resonator. A micro-strip split ring resonator includes a first H-shaped micro-strip signal line(13) having a first opened slit at one end and a closed slit at the other end, a second H-shaped micro-strip signal line(14) having an inner cap(31) spaced apart from the first micro-strip signal line, and a second opened slit formed on the second micro-strip signal line opposite to the first opened slit. A coupling intensity of the first and second micro-strip signal lines is increased by the first and second opened slits or the inner cap.
