A compact multiple-band antenna for wireless devices having a plurality of operating frequency bands is disclosed. In one embodiment, the multiple-band antenna includes a ground area, a first radiating member having a first end, an intermediate portion, and a second end. The first radiating member is configured to cooperatively receive and substantially radiate RF signals at a first, second, and third resonant frequencies. The first end of the first radiating member is electrically connected to the ground area and the intermediate portion of the first radiating member is electrically connected to a first feed point. The antenna includes a second radiating member having a first end and a second end. The second radiating member is configured to cooperatively receive and substantially radiate RF signals at the first, second, and third resonant frequencies. The first end of the second radiating member is electrically connected to the second end of the first radiating member; a third radiating member having a first end and a second end and cooperatively receiving and substantially radiating RF signals at the first, second, and third resonant frequencies, wherein the first end of the third radiating member is electrically connected to the second end of the second radiating member; and a fourth radiating member having a first end, an intermediate portion, and a second end and providing a fourth resonant frequency, wherein the first end of the fourth radiating member is electrically connected to the second end of the third radiating member, the intermediate portion of the fourth radiating member is electrically connected to a second feed point, and the second end of the fourth radiating member is unconnected. |
