A coupling-type antenna includes a substrate having opposing top surface and bottom surface, a monopole antenna element formed on the top surface of the substrate for transmitting a first current and having a feed point and a radiator and a conductor respectively extended from the feed point, and a coupling body formed on the bottom surface of the substrate opposite to the monopole antenna element for transmitting a second current. Further, the transmitting direction of the first current in the monopole antenna element is opposite to the transmitting direction of the second current in the coupling grating body.
