Abstract

A sensor has an antenna. The antenna includes a radiation source and a wave guide. The radiation source is formed on a substrate. The wave guide internally propagates electromagnetic waves radiated from the radiation source and radiates the electromagnetic waves as a beam. The wave guide has a radiation-side opening in which a first direction and a second direction are orthogonal to each other, and the second direction is longer than the first direction. In a cross-sectional shape of the beam, perpendicular to a radiation direction of the beam radiated from the wave guide, a first direction and a second direction are orthogonal to each other, and the second direction is narrower than the first direction.
