STEPPED IMPEDANCE SLOT RESORNATOR DESIGN METHOD THEREOF AND FILTER DESIGN METHOD WITH THE SAME

摘要

The present invention relates to a multi-stage impedance slot resonator, a design method thereof, and a filter design method using the multi-stage impedance slot resonator. The multi-stage impedance slot resonator comprises: a signal line formed on an upper surface of a dielectric; and one pair of slot lines formed in an eddy shape since the pair of slot lines spaced apart at predetermined intervals from both sides of the signal line in a ground line formed on the lower surface of the dielectric. In the pair of slot lines, a configuration in which a plurality of stages are adjusted by slot widths is provided so that the ratio of a first resonant frequency and second resonant frequency of the resonator may be changed to suit the purpose by adjusting the slot width of each stage of the slot lines.
