Abstract

PURPOSE:To reduce the size of an element by providing a magnetic film between the line conductor of a strip line and a substrate and thereby improving the shortening coefficient of wavelength. CONSTITUTION:A magnetic film 7 is provided between the line conductor 6 of a strip line and a substrate 4. In a delay element of such a constitution, the velocity of electromagnetic waves moving in a medium of coefficient of electromagnetic dielectric constant epsilon and magnetic permeability mu is v=(epsilon.mu)-1/2. Accordingly, delay time can be enlarged by the magnetic film 7 having large magnetic permeability. As the delay element is strip line type, distribution of magnetic flux is uniform and influence of frequency upon delay characteristics is small. Thus, the shortening coefficient of wavelength is improved and thereby the size of the element can be made small.
