  • Patent number: 8711053
    Abstract: Provided is an antenna device, having a small and simple configuration, which reduces connection resistance in connections between a film antenna element and a power feeding unit. An antenna device comprises a nonconductive transparent film, which is an insulating substrate having a prescribed optical transmission factor, an antenna element that is formed, upon the transparent film, from transparent conductive material, which is a conductive material having a prescribed optical transmission factor, and a non-transparent conductive power feeding wire. The transparent film and the transparent conductive material are doubled over and pressed upon a portion of one side of the antenna element, which forms a square dipole antenna, such that the transparent conductive material is on the inside, and the power feeding wire is sandwiched therein. By being doubled over, the transparent conductive material has an overlap portion, the two sides whereof electrically connect to one other.

  • Patent number: 8547279
    Abstract: Provided are a device and a method that can classify an incoming wave and can correctly distinguish the position of an originating device, even in a multipath environment. A principal vertically polarized wave arrival direction sensing unit (104-1) and a principal horizontally polarized wave arrival direction sensing unit (104-2) respectively sense the arrival direction of a principal wave by sensing the arrival direction in which the maximum reception level is obtained. An incoming wave classifying decision unit (108) determines that a direct wave has arrived when the difference between the principal wave arrival direction sensed by the principal vertically polarized wave arrival direction sensing unit (104-1) and the principal wave arrival direction sensed by the principal horizontally polarized wave arrival direction sensing unit (104-2) is within a prescribed threshold value, and determines that a direct wave has not arrived when the difference is greater than the threshold value.
