Document Type and Number:
Japanese Patent JP2008502205
Kind Code:
A
Abstract:
A dipole antenna for a wireless communication device, which includes a first conductive element superimposed on a portion of and separated from a second conductive element by a first dielectric layer. A first conductive via connects the first and second conductive elements through the first dielectric layer. The second conductive element is generally U-shaped. The second conductive element includes a plurality of spaced conductive strips extending transverse from adjacent ends of the legs of the U-shape. Each strip is dimensioned for a different center frequency lambda 0 . The first conductive element may be replaced by a coaxial feed directly to the second conductive element.
