摘要： An antenna having a waveguide structure and comprising a base of a thin flat metal; a radiation plate of a thin flat metal arranged in parallel with the base at a distance from the base; and a plurality of thin flat metal side walls secured to the base and radiation plate, and arranged in the space between the base and the radiation plate so as to form a plurality of waveguides connected to each other. The radiation plate and the side walls are joined by spot-welding at given intervals. The base and the side walls are preferably in the form of a single block made of a metallic material.
