Abstract
To provide a radar module used for a speed measuring device or the like, in which dispersion of intensity distribution of electromagnetic waves emitted from the radar module via a lens is small, the radar module using a substrate with a plane antenna formed on a surface of the substrate includes: a lens having one end face that is plane and another end face that is spherical. In the radar module, a plane side of the lens is disposed to contact the plane antenna, and a spherical side of the lens is disposed in a remote field of the plane antenna.
