An antenna for a portable computer is disclosed. The antenna includes a ground element, a first and second radiating elements, and a driven element. The ground element is linearly extended on a surface of a circuit substrate. The first radiating element, which is adapted to a first frequency band, includes a horizontal-portion pattern extending substantially parallel to the ground element on the surface of the circuit substrate. The driven element, which is provided on the surface of the circuit substrate between the ground element and the horizontal-portion pattern, supplies electromagnetic-wave energy to the first radiating element. The second radiating element is provided on the surface of the circuit substrate between the ground element and the horizontal-portion pattern. The second radiating has contact with the driven element, and is adapted to a second frequency band and a third frequency band that is higher than the second frequency band.
