Total Claims: 14
Claim 1
Independent Claim
131 words
A parasitic element for use with an internal substrate antenna in a wireless communication device having one or more signal or power transfer conductors or signal feeds located adjacent to said antenna, wherein said substrate antenna comprises: one or more conductive traces supported on a dielectric substrate having a predetermined thickness; said supporting substrate is mounted offset from and generally perpendicular to a ground plane associated with the wireless device; and said parasitic element comprises: at least one layer of conductive material disposed adjacent to one or more of said conductors in a region adjacent to said antenna, having a pre-selected width relative to said conductors, and a pre-selected length along said conductors sufficient to prevent energy from being coupled between said antenna and conductors in the region of said layer.
