Title:
RADOME FOR ON-BOARD RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/179358
Kind Code:
A1
Abstract:
A radome 1 for an on-board radar device is provided with a heater wire 3 arranged in parallel lines with a space therebetween in a surface direction of a substrate having an electromagnetic-wave transmission property. A line pitch d between the parallel lines of the heater wire 3 in an electromagnetic-wave transmission region R of the substrate is set 0.2 to 2.5 times the wavelength of electromagnetic waves of the radar of the on-board radar device. The surface occupancy of the parallel lines of the heater wire 3 in the electromagnetic-wave transmission region R of the substrate is set greater than 10% and less than or equal to 35%. The present invention provides a radome for an on-board radar device with which it is possible to obtain an electromagnetic-wave transmission property required of a radome, and to melt snow effectively with a high heater performance.
