Abstract: In the present invention, a radio communication antenna having a narrow beam width comprises: a reflecting plate provided in the form of a plate of rectangular shape; and one radiating module disposed on the reflecting plate and generating x-polarized waves. Here: the radiating module comprises four radiating elements of dipole structure; the four radiating elements are respectively disposed at four edge portions of the reflecting plate, and each comprises two radiating arms placed in the direction extending along both sides relative to the edges; and, among the four radiating elements, those radiating elements that face each other diagonally are linked in movement so as to generate one of the x-polarized waves.
