Abstract
An antenna section is housed in a housing space which is defined by a radome and a housing, and provided with a transmitting antenna that transmits radar waves composed of radio waves of a predetermined frequency and a receiving antenna that receives the radar waves. The radome has a transmission section that is a portion transmitting the radar waves and an attenuation section that is a portion attenuating the radar waves. The attenuation section includes a first attenuation layer formed of a material for attenuating the radar waves. The first attenuation layer has a thickness that is 2n−1 times (n is a natural number) of one-quarter of a wavelength of the radar waves in the first attenuation layer.
