A twin monopole antenna is disclosed. This twin monopole antenna comprises: a substrate having a first surface and a second surface; an upper ground plane that is located on the first surface of the substrate and comprises: a first ground plane, a second ground plane and a third ground plane; a lower ground plane that is located on the second surface of the substrate and comprises: a fourth ground plane; and an inverted-U shaped ground plane having a hollow rectangular surface; a first radiating line located on the first surface of the substrate, wherein a first included angle is located between the first radiating line and the second ground plane; and a second radiating line located on the first surface of the substrate, wherein a second included angle is located between the second radiating line and the second ground plane, and an interval between the first radiating line and the second radiating line. There is a valuable implementation in industrial field because the twin monopole antenna of the present invention can be operated in high frequency bands, and meanwhile provide a broader radiating and receiving pattern. Moreover, the present invention can be printed on a substrate, so that the present invention is easy to be integrated with other associated circuitries and the cost is lowered.
