MICROSTRIP FILTER OF SLOT TYPE

摘要

PURPOSE: A microstrip filter of a slot type is provided to enhabce capacitance coupling or inductance coupling between resonators, thereby controlling a notch phenomenon and a frequency waveform property. CONSTITUTION: A housing(110) comprises an input port(102) and an output port(104) in both sides. An upper part cover(106) and a lower part cover(108) cover an upper side and a lower side of the housing. A first printed circuit board(PCB)(120) is installed in the housing. A plurality of first resonators is formed in the first PCB. A second PCB(130) comprises a plurality of second resonators. A part of the second resonators is arranged to be crossed with the first resonators. A dielectric substance forms a transmission path of a wireless frequency signal as zigzag.
