Abstract
The present invention is an antenna provided with: a plurality of radiating parts formed on a base plate; a waveguide tube inside of which radio waves emitted from the radiating parts propagate; a lens having a plurality of curved surfaces having a substantially hyperbolic shape and disposed in an opening of the waveguide tube; and a protruding part formed in a tapered shape between the plurality of radiating parts. The tip of the protruding part is formed at a position lower than an opening surface.
