Patent ID: 8059055

Claim:
An antenna comprising: a first radiating element having opposite feeding and grounding end portions, said feeding end portion configured to connect to a transceiver; a second radiating element having opposite feeding and grounding end portions, each of which is coupled to a respective one of said feeding and grounding end portions of said first radiating element; and a conductive arm coupled to said feeding end portion of said second radiating element, wherein: said second radiating element and said conductive arm are configured to resonate in a first frequency range, and a first current path flows through said conductive arm and said second radiating element when the antenna operates in the first frequency range; said second radiating element is configured to resonate in a second frequency range, and a second current path flows through said second radiating element and does not flow through said conductive arm when the antenna operates in the second frequency range; and said first radiating element is configured to resonate in a third frequency range, and a third current path flows through said first radiating element when the antenna operates in the third frequency range.
