Document Type and Number:
WIPO Patent Application WO2003017421
Kind Code:
A3
Abstract:
A fractal antenna is patterned out of a conductive layer (e.g., Cu, Au, ITO, etc.), and is provided between first and second opposing substrates of a vehicle windshield. A polymer inclusive interlayer functions to both protect the fractal antenna(s) and laminate the opposing substrates to one another. In other embodiments, a multiband fractal antenna is provided which includes a first group of triangular shaped antenna portions, and a second triangular shaped antenna portion(s), wherein each of the triangular shaped antenna portions of the first group is located within a periphery of the second triangular shaped antenna portion. The first group of antenna portions transmits and/or receives at a first frequency band, while the second antenna portion(s) transmits and/or receives at a second frequency band different than the first band.
