Title: Delay element
Inventor: FUJIWARA YOSHIAKI
IPC: H01P9/00
Filed: 1981-09-09
Abstract: PURPOSE:To miniaturize a strip line type delay element, by decreasing the external inductance by use of a magnetic film pattern, and decreasing a velocity of propagation of an electromagnetic wave propagating through a strip line. CONSTITUTION:With an insulating layer 4 between, under a conductive film 1, a magnetic film 5 is formed in the same shape as the conductive film 1. In this case, the insulating layer 4 insulates the conductive film 1 from the magnetic  film 5, and a material which consists of an inorganic material such as SiO2, etc., or an organic material such as polyimide, and has high insulation resistance is used. On the other hand, as for the magnetic film 5, a soft magnetic material such as ''Permalloy  '' is used. In such a structure, since a material whose magnetic permeability is high is used as a magnetic film under the conductive film 1 forming a strip line, a contribution portion of the external inductance is large, and accordingly, a velocity of an electromagnetic wave propagating through the strip line is decreased. Accordingly, a delay element can be miniaturized.
