Abstract
A multi-band antenna is arranged on a housing with a first surface, a second surface opposite to the first surface, and a third surface connecting the first and second surfaces, which has a first radiating conductor and a parasitic element formed as an elongated shape and arranged on the first surface. A trap circuit connects the first radiating conductor and the parasitic element. A ground portion is arranged on the second surface. A second radiating conductor is arranged on the third surface and spaced from the first radiating conductor and the ground portion, which is formed as an elongated shape. A feeding conductor with a feeding point connects the first and second radiating conductors. The multi-band antenna obtains a low frequency band through the cooperation of the first radiating, the parasitic element and the trap circuit, and a high frequency band through the second radiating conductor and the parasitic element.
