PROBLEM TO BE SOLVED: To provide an antenna which is easier to assemble than before and has its beam width widened. SOLUTION: The antenna includes a reflector, a first microstrip antenna element disposed on the reflector, and a first parasitic element disposed on the first microstrip antenna element. The first parasitic element has end parts bent toward the reflector side, both the end parts being at both ends in a direction along a line connecting together a point where a feeder for supplying excitation electric power to the first microstrip antenna element is connected and a center point of the first microstrip antenna element. The first parasitic element is in a rectangular shape when spread. A dielectric substrate arranged on the first microstrip antenna element is provided, and the first parasitic element is fixed to a surface of the dielectric substrate on the side of the reflector.
