ABSTRACT:
An automotive radar having a high level of azimuth accuracy and a broad detectable range by virtue of preventing leaks of unnecessary waves to receiving antennas is to be provided. A transmitting array antenna1and receiving array antennas2a, 2bare arranged on an antenna plate (grounding conductor plate)3which serves to ground the antennas, and radio wave absorbers4are arranged on two sides of the edges15of the antenna plate3. The radio wave absorbers4may be configured of, for instance, a sponge material containing radio wave absorbing grains.
