Patent ID: 8054229

Claim:
An antenna comprising: a first U-shaped antenna element formed in a band-like shape for a first frequency band; a second antenna element not physically connected to said first antenna element and formed in a band-like shape for a second frequency band, and having one end portion partially overlapped with one end portion of the U-shaped first antenna element, the one end portion of the second antenna element extending in a direction opposite to a direction of extension of the one end portion of the U-shaped first antenna element; and a dielectric element sandwiched between the first antenna element and the second antenna element at that portion where the first antenna element and the second antenna element overlap with each other, wherein an other end of the second antenna element serves as a power feeding end, wherein the first antenna element and the second antenna element overlap at an end of a leg of the U-shaped first antenna element in an area of the dielectric.
