Abstract
A method of adjusting a frequency response in a filter device of a three-conductor type having a pair of stacked dielectric substrates with a plurality of strip-line resonator conductors being sandwiched therebetween, wherein the frequency adjusting of the filter is performed by partially removing the ground conducting layer provided on the peripheral portion of each dielectric substrate at regions corresponding to the open circuit ends, or to the open circuit ends and the short circuit ends of the resonator conducting layers.
