  • Patent number: 8149593
    Abstract: A radiation level reducing device, including: a metal plate for covering surface of an electromagnetic wave generation source for radiating an electromagnetic wave; a cover region, set within a plane of the metal plate, for covering the surface; and a plurality of slits formed to a band-shape in the cover region, and spaced apart from each other, wherein each of the plurality of slits includes, a drawing slit extending towards a central part of the cover region from an intense electric field position where an electric field generated in between the electromagnetic wave generation source by the electromagnetic wave is stronger than other positions at an outer periphery of the cover region, and a coupling slit extending so as to line in parallel to another slit from an end in the central part direction of the cover region in the drawing slit.

  • Publication number: 20120024587
    Abstract: There is provided a radiation amount reducing device including a plurality of slit formed to a band-shape in a cover region, which is set in a plane of a metal plate capable of entirely covering at least one surface of an electromagnetic wave generation source, and spaced apart from each other, each of the plurality of slits including a drawing slit formed extending from a ferromagnetic field position towards a central part of the cover region and a coupling slit formed extending in parallel with another slit from an end in a central part direction of the cover region in the drawing slit.

  • Patent number: 4454514
    Abstract: A linear polarization strip antenna which comprises a dielectric substrate whose backside is fitted with a conductive ground film, a power supply strip line which is formed of a conductive film and on the surface of the dielectric substrate, and a linear polarization radiation element. The strip line and radiation element are electromagnetically coupled together. A diode is connected between a top end of the strip line and a ground terminal. The top end of the strip line is selectively set at an open or grounded state according to the conductive state of the diode to vary the mode of electromagnetic coupling between the strip line and radiation element, thereby changing the direction in which the radiated electromagnetic wave is polarized.
