  • Patent number: 10974661
    Abstract: A vehicle decorative part includes a decorative main body and a heater. The decorative main body is configured to be attached to a vehicle at a front side in a transmission direction of millimeter waves from a millimeter wave radar and has a millimeter wave transparency. The heater has a heating element that emits heat when energized. At least a part of the heating element is located in an irradiation region of the millimeter waves in the heater. As a millimeter wave attenuation reducing configuration that reduces attenuation of the millimeter waves passing through the heater, the heating element is incorporated in the heater in a condition where an area proportion of an area of a section of the heating element that occupies the irradiation region to an area of the irradiation region is set such that an attenuation amount of the millimeter waves is less than or equal to a permissible value.

  • Patent number: 10693224
    Abstract: A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.
