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 stripline resonator conductors being sandwiched therebetween, wherein the frequency adjusting of the filter is performed by partially removing an open circuit end of each resonator conductor and at need by adding an compensating conductor member to the partially removed open circuit end portion of each resonator conductor.
