LAMINATED TYPE DIELECTRIC FILTER

摘要

PURPOSE: A laminated type dielectric filter is provided to improve a skirt characteristic by forming conductive patterns on an upper part or a bottom part or both the upper and the bottom parts of resonator patterns. CONSTITUTION: A laminated type dielectric filter includes a dielectric block(120), a plurality of ground electrodes(150), an input and an output electrode(130,140), internal ground patterns, resonator patterns, and inductor patterns. The dielectric block(120) is formed with a plurality of dielectric sheets. The ground electrodes(150) are formed on a front and a rear side of the dielectric block(120). The input and the output electrodes(130,140) are formed on both sides of the dielectric block(120). The internal ground patterns are connected to the ground electrodes(150). The resonator patterns are formed between the internal ground patterns in order to be connected to the ground electrodes(150). The inductor patterns are formed with a shape of a closed loop in order to form the inductance between plural resonators.
