1. A radio communication antenna having a narrow beam width, the radio communication antenna comprising:

  • a reflective plate provided in the form of a tetragonal plate; and

    a radiation module installed on the reflective plate and configured to generate crossed polarization,wherein the radiation module comprises four radiation elements of a dipole structure, the four radiation elements are arranged at four corners of the reflective plate, respectively, two radiation arms extend along two edges with respect to one of the corners, and pairs of two radiation elements of the four radiation elements, which face each other in the diagonal direction interwork with each other and generate one polarization in the crossed polarization, anda separate radiation module that installed at a central location of the radiation module formed by the four radiation elements on the reflective plate and generates an additional crossed polarization which combines with the crossed polarization to form a radiation beam having a predetermined beam width of the radio communication antenna, and the additional crossed polarization has the same frequency as the crossed polarization.
