A method of manufacturing a single mode optical fiber formed of a silica-based glass and including a glass part having a central core and a cladding region. In these tags, the radio frequency is transmitted through a resonance circuit without the need for direct connection of a conducting pattern or conducting patterns, but rather via a dielectric film which is adjacent to the conducting pattern or separates the conducting patterns. The lightpipe is coated with a thin layer of visible-light transparent material which is doped with organic dye molecules. The floating bracket enables expansion or contraction of the vehicle body panel to take place.
