A high-directional wide-bandwidth antenna is disclosed. The high-directional wide-bandwidth antenna includes a first element, a first radiating body, a second radiating body, a third radiating body, and a fourth radiating body. The first element has a first feeding point, wherein its equivalent reactance is inductive. One end of the first radiating body is connected to the first element and the other end of the first radiating body is a coupling surface. The second radiating body has a second feeding point and is extended through the second feeding point to the coupling surface so that the energy is transferred between the first radiating body and the second radiating body through the coupling surface. The first resonant frequency is attained by the first radiating body and the second radiating body, and the second resonant frequency is attained by the third radiating body and the fourth radiating body.
