Abstract: A multiband antenna for an electronic device includes a resonance radiation body, a grounding end, and a spread spectrum portion. The resonance radiation body receives a first electromagnetic wave signal at a first frequency (known as fundamental frequency). The grounding end and the electronic device are connected. The spread spectrum portion is disposed between the resonance radiation body and the grounding end. The spread spectrum portion includes first and second shunting bodies to form a loop bypass between the resonance radiation body and the grounding end and thereby decrease and increase the first frequency by a specific frequency value so as to define a bandwidth equal to two times the specific frequency value. Hence, the electronic device receives a second electromagnetic wave signal at any frequency within the bandwidth. Since the spread spectrum portion defines the bandwidth, the electronic device can receive the first and second electromagnetic wave signals.
