Title:
ELECTROMAGNETIC DELAY LINE INDUCTANCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2005/043750
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a concentrated constant type electromagnetic delay line inductance element which can easily be made as an ultra-small chip shape and obtain a preferable connection state at each interval. [MEANS FOR SOLVING PROBLEMS] Spiral-shaped inductors L0B, L4A, L4B are formed on a first insulating substrate (15) and the inductor L4A is connected in series to the inductor L4B. Spiral-shaped inductors L1, L3, L5 are formed on a second and a third insulating substrate (22, 33). Spiral-shaped inductors L2A, L2B, L6A are formed on a fourth insulating substrate (41) and the inductor L2A is connected in series to the inductor L2B. The first to the fourth insulating substrates (15-41) are stacked on one another and the inductors L0B to L6A are connected in the longitudinal direction. The inductors L2A and L2B and the inductors L4A and L4B are divided into two portions in the horizontal direction so as to form one interval and positively connected to the preceding and the following interval not divided in the horizontal direction.
