摘要： A microwave strip line filter has a pair of dielectric substrates being stacked and bonded to each other, which are similar in pattern but different in dimension. The dielectric substrates are bonded to each other with spots of bonding agent applied to resonant electrodes on one of the dielectric substrates, thereby preventing the electric characteristic from being adversely affected by bonding agent when the dielectric substrates are superimposed and bonded to each other. The dielectric substrates are made of ceramic materials having relative dielectric constants in order to easily and exactly obtain various desirable resonant frequency characteristics by using resonant electrodes having the same pattern.

摘要： A dielectric filter in which input/output coupling electrode layers are arranged on the surfaces of the substrate sections, separated from the resonating conductors by an adjustable distance, the coupling capacitance of the device can be chosen within a wide range of selection because of the relatively large area of the surfaces. The dielectric filter comprises an interstage coupling electrode layer which is formed on a temporary surface of a dielectric substrate that has a relatively large area and becomes internal in the final product with a predetermined but adjustable distance from a pair of resonating conductors arranged in the dielectric substrate.
