Abstract:
The present invention provides a multiple band antenna, including a first radiation element adapted to resonate at a first resonant frequency band by employing a resonant length, which is reduced by a coupling effect with a neighboring radiation element, a power feed unit coupled to one lower side of the first radiation element, a first inductor coupled in series to the other lower side of the first radiation element, a second radiation element adapted to face the first radiator to thereby obtain the coupling effect, wherein the second radiation element has a predetermined lower portion coupled to the first inductor, a second inductor having one end coupled in series to a predetermined upper portion of the second radiation element, and a third radiation element coupled to the other end of the second inductor, wherein the third radiation element operates as one radiation element together with the second radiation element and resonates at a second frequency band.
