Abstract
To realize an element presenting a constant impedance throughout an extremely wide frequency range and a circuit supplying a high frequency signal having a constant phase throughout the same wide frequency range, a ferrite-loaded line element, a real part of a terminal complex impedance of which is substantially constant, is provided. A partial inclination of an imaginary part of the terminal complex impedance is compensated by providing a pure reactance element, in combination therewith As a result, in an extremely wide frequency range exceeding a natural magnetical resonant frequency, a ferrite-loaded constant impedance element and a constant phase circuit comprising this constant impedance element can be attained.
