Abstract

PURPOSE:To make the device small-size, by extending a center conductor into a strip line and providing a capacitor between one end of the strip line and an earth conductor. CONSTITUTION:Two ferrites are put on a soft magnetic substance 12, which operates as an earth conductor, through a shield plate, and center conductors are arranged between them, and a magnetic field is applied from above by a disc-shaped permanent magnet 3. A print board 19 is provided on the soft magnetic substance 12 to make it easy to solder a chip capacitor 18. The chip capacitor 18 is provided between each conductor 13 and the print board 19. Otherwise, a disc-shaped ceramic type capacitor is used and is soldered after binding lead wires. A shield plate may be used as the earth conductor.
