Summary: | Provided is a patch antenna for a surface wave of a metal plate which can transmit or receive a radio wave in an RF shadow zone. According to an embodiment of the present invention, the patch antenna for a surface wave comprises: a dielectric layer inserted between a plane layer and a pattern layer to form an electromagnetic field by the surface wave; the plane layer arranged on a first surface of the dielectric layer, and preventing the electromagnetic wave formed on the dielectric layer from being emitted; and the pattern layer arranged on a second surface of the dielectric layer, having a window formed to be designed by considering a wavelength of the surface wave, and being in contact with the metal plate to transmit the surface wave.
