LAMINATED DIELECTRIC FILTER AND MANUFACTURE OF THE SAME

Document Type and Number:

Japanese Patent JP3524630

Kind Code:

B2

Abstract:

PURPOSE: To provide a laminated dielectric filter having a chip upper face pattern extremely similar to conventional one and further can be produced by a no-gap system.
CONSTITUTION: The upper face pattern satisfies following conditions. A chip upper face is rectangularly formed on the conditions of -d≤x≤d and -k≤y≤k. The pattern of one terminal conductor film 13 is formd in the area of b≤x≤d and h≤y≤i and oppositely, the pattern of another terminal conductor film 14 is rotationally symmetrically formed at 180° with a coordinate origin as a center. The pattern of a half 12a of a ground conductor film 12 is formed in the area of -c≤x≤a and 0≤y≤j, the area of -c≤x≤-a and j≤y≤k and the area of -d≤x≤-c and h≤y≤i and oppositely, the pattern of a remaining half 12b of the ground conductor film 12 is rotationally symmetrically at 180° with the coordinate origin as the center.
