SPLIT RING RESONATOR AND ULTRA-NARROW BANDPASS FILTER USING THE SAME

摘要

PURPOSE: A split ring resonator and an ultra-narrow bandpass filter using the same are provided to maintain good insertion loss by forming a metal pattern on a dielectric having low dielectric loss. CONSTITUTION: A first dielectric substrate(101) has a first thickness. A second dielectric substrate(102) is laminated on the first dielectric substrate. The second dielectric substrate is made of a material having a dielectric loss lower than that of the first dielectric substrate. A circular metal pattern is formed on the second dielectric substrate. The circular metal pattern is resonated according to design frequency.
