Title:
RADOME FOR VEHICLE-MOUNTED RADAR DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/092985
Kind Code:
A1
Abstract:
This radome 1 for a vehicle-mounted radar device comprises: an insulating transparent substrate 2 that is visible from a front-surface side, a discontinuous metal film 3 that has electromagnetic wave transparency and metallic luster and is formed on the rear-surface side of the transparent substrate 2 in a mark shape, and a background color layer that is provided on the rear surface side of the discontinuous metal film 3 across the entire surface of an area corresponding to the mark shape and an area around the mark shape in a surface view. The discontinuous metal film 3 is preferably formed as an electroless plating metal film on a modified surface 22 formed on the transparent substrate 2 in a shape corresponding to the mark shape. The present invention makes it possible to manufacture without a silk screen printing process, enhance manufacturing efficiency, reduce manufacturing cost, obtain even electromagnetic wave transparency, and reliably prevent radar performance reduction in a vehicle-mounted radar device.
