  • Patent number: 11165157
    Abstract: An antenna device includes a ground plate, a patch portion disposed parallel to the ground plate with a particular spacing, a plurality of short circuit portions that electrically connect the patch portion to the ground plate, and a loop portion which is a loop shaped conductor member at a particular spacing from an outer edge portion of the patch portion. The patch portion has an area which forms an electrostatic capacitance that causes parallel resonance with an inductance provided by the short circuit portions at a particular target frequency. The loop portion is formed with a perimeter length which is an integral multiple of the wavelength of radio waves at the target frequency. A feed point is disposed on the loop portion, and current is supplied to the patch portion through the loop portion.

  • Publication number: 20210256728
    Abstract: In an object detection apparatus for detecting a position of an object based on at least measured distances to the object as measurement results by a plurality of ranging sensors, a speed difference calculator calculates, for each of candidate points representing the position of the object, a relative speed difference between the relative speeds of the candidate point acquired from the plurality of ranging sensors. The candidate-point determiner determines that a candidate point of the candidate points, the relative speed difference of which is equal to or greater than a predetermined value, is a virtual image of the object. An object detector detects the position of the object based on positions of the candidate points each determined to be a real image after removal of the candidate points each determined to be a virtual image from all of the candidate points.
