Elliptic function Band-Pass Filter Using the microstrip split ring resonators

摘要

An elliptic function band-pass filter using a micro-strip ring resonator is provided to improve a coupling efficiency by increasing capacitance and equivalent capacitance, thereby improving the quality of the resonator. A first resonator(100) connected to an input line and a second resonator(200) connected to an output line are arranged at a first interval in such a way that open slit(40) of a first micro-strip signal lines are opposite to each other. Under the first and second resonators, a second interval is formed, in which a third resonator(300) and a fourth resonator(400) are arranged. The third and fourth resonators form a third interval to produce a magnetic coupling.
