Abstract
Provided is an antenna which includes a plurality of radiating portions which are formed on a substrate and a plurality of dielectric lenses for respectively converting a spherical wave radiated from each radiating portion into a plane wave, wherein the shape of a cross section of each dielectric lens perpendicular to a radiation direction of a beam is formed in a shape which radiates a beam which is narrower in a second direction than in a first direction orthogonal to the second direction, and the plurality of dielectric lenses are arranged side by side in the second direction so that beams radiated from the respective dielectric lenses are synthesized.
