ABSTRACT:
A linearly polarized antenna includes a dielectric substrate, a ground conductor which is overlapped on one surface of the dielectric substrate, an antenna element made of linearly polarized, which is formed on an opposite surface of the dielectric substrate, a plurality of metal posts in which one end side of each of the plurality of metal posts is connected to the ground conductor, the plurality of metal posts piercing through the dielectric substrate along a thickness direction thereof, another end side of each of the plurality of metal posts being extended to the opposite surface of the dielectric substrate, the plurality of metal posts being provided at predetermined intervals to form a cavity so as to surround the antenna element, and a conducting arm which short-circuits the other end of the plurality of metal posts along a line direction of the plurality of metal posts on the opposite surface side of the dielectric substrate, the conducting arm being provided while extended by a predetermined distance toward a direction of the antenna element, the conducting arm having a triangular portion.
