Title:
RADAR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/018182
Kind Code:
A1
Abstract:
Provided is an antenna apparatus with an antenna unit. The antenna unit transmits and receives a radar wave formed by an electromagnetic wave. A magnetic body is disposed at a position through which the radar wave transmitted and received by the antenna unit passes. A magnet produces a magnetic field along the direction in which the radar wave propagates in the magnetic body. A polarizing filter is disposed on the opposite side of the magnetic body with respect to the antenna unit. Thus, interference between the emitted wave and a reflected wave caused by a cover such as a bumper is minimized regardless of the shape of the cover.
