In a slot array antenna including a dielectric plate for delaying the propagation of radio waves in a plane perpendicular to the vertical direction, a radome covers an opening formed by the dielectric plate and the reflector. The material of the radome is made of a material having the same dielectric constant as the dielectric plate, and its shape is such that it has a surface parallel to the dielectric plate, so that it is integrated with the dielectric plate to transmit radio waves. A slot array antenna characterized by comprising a dielectric material for propagation delay.
