Electrically-conductive articles are prepared to have electrically-conductive metallic grids and electrically-conductive metallic connectors (BUS lines) on one or both supporting sides of a transparent substrate. The electrically-conductive metallic connectors are designed with one metallic main wire that comprises two or more adjacent metallic micro-wires in bundled patterns. These bundled patterns and metallic micro-wires are designed with specific dimensions and configurations to provide optimal fidelity (or correspondence) to the mask image used to provide such patterns. The electrically-conductive articles can be prepared using various manufacturing technologies and can be used as parts of various electronic devices including touch screen devices. The electrically-conductive metallic grids and connectors can be prepared and designed using various technologies that are amenable to obtaining very fine lines in predetermined patterns.
