Provided is a ultra-wideband dual linear polarized wave waveguide antenna for communication having a wideband matching structure in which the inner peripheral surface of the first polarized wave filtering unit or the second polarized wave filtering unit, which filters a first polarized wave or a second polarized wave entering the dual linear polarized wave waveguide antenna and orthogonal to each other, are tapered such that a diameter of the inner peripheral surface becomes smaller, and having an extended path so as to adjust the first polarized wave and the second polarized wave so that they are in-phase. By doing so, the ultra-wideband dual linear polarized wave waveguide antenna is capable of both receiving and transmitting and thus can be used for communication, and can adjust skew angles without being mechanically rotated.
