摘要

Methods of forming conductive lines, antennas, and wireless communications devices, and related conductive lines, antennas and wireless communications devices are described. In one aspect, a substrate having an outer surface is provided. A first layer of conductive material is formed over the outer surface. A second layer of conductive material is formed over only portions of the first layer. Using the second layer as a masking layer, the first layer is etched selectively relative thereto to provide a conductive line comprising the first and second layers. Preferably, the first layer is more conductive than the second layer. In a preferred implementation, the conductive line constitutes an antenna construction which is suitable for use in a wireless communications device. In another preferred implementation, an antenna, an integrated circuitry chip, and a battery are mounted on a substrate and operably interconnected to provide an integrated circuitry chip, with the antenna being formed as described above.
