  • Printed circuit with inductively coupled printed coil elements and a printed element forming a mutual inductance therewith
    Patent number: 4063201
    Abstract: A printed circuit including a first conductor formed on an insulating plate as an inductance element, a second conductor formed on the insulating plate as an inductance element which is inductively coupled to the first element, and a common conductor formed on the insulating plate between the first and second elements and mutually inductively coupled to the first and second elements to provide a predetermined desired coefficient of coupling between the first and second elements. A preferred detailed form of the invention additionally includes printed capacitor elements in circuit with the inductance elements to provide an electric band-pass wave filter.
