Abstract
A slot array antenna comprises a slot array antenna main body () and a dielectric cover (). The slot array antenna main body () has a slot plate (). A main beam () having radiation directivity, extending in a direction inclined a tilt angle θ alone from a direction normal to a plane Pof the slot plate () is set to the slot array antenna main body (). The dielectric cover () has an inclination angle α formed by an outer plane Pand an inner plane Pand is comprised of a dielectric material having a refractive index n. The inner plane Pof the dielectric cover () is provided so as to oppose to the slot plate () of the slot array antenna main body (). Thus, the main beam () having the radiation directivity is transmitted through and refracted by the dielectric cover (), so that the tilt angle θ is corrected to allow the main beam to extend in a direction orthogonal to the outer plane Pof the dielectric cover ().
