Abstract
Included are: a radar main unit for emitting a radar wave and receiving a reflection wave of the radar wave reflected by an object; and a dielectric substrate in which multiple matching layers each having a protruded shape are regularly arranged on one surface of the dielectric substrate, and the radar wave emitted from the radar main unit enters the multiple matching layers in a state where the other-surface side of the dielectric substrate is attached to a windshield.
Claims14
A radar device comprising:
- a radar main unit to emit a radar wave and receive a reflection wave of the radar wave reflected by an object;
- and
- a flexible dielectric substrate in which multiple dielectric units each having a protruded shape are regularly arranged on one surface of the dielectric substrate, and the radar wave emitted from the radar main unit enters the multiple dielectric units in a state where another-surface side of the dielectric substrate is attached to a curved dielectric surface,
- wherein the dielectric units each protrude stepwise and a thickness of the dielectric substrate on the another-surface side allows the dielectric substrate to be attached along the curved dielectric surface.
