A tag antenna structure of an information carrier includes a carrying sheet and a tag antenna disposed on the carrying sheet. An outer lateral edge of the carrying sheet is symmetrical to a first central axis, and a distance between the outer lateral edge of the carrying sheet and the first central axis is defined as a first outer diameter. The tag antenna includes an annular segment and two extending segments respectively extending from two end portions of the annular segment. An outer lateral edge of the annular segment is symmetrical to a second central axis, and a distance between the outer lateral edge of the annular segment and the second central axis is defined as a second outer diameter that is smaller than the first outer diameter. The second central axis and the first central axis have an offset distance there-between that is larger than zero. 1. An information carrier , comprising:a carrying sheet defining a first central axis, wherein an outer lateral edge of the carrying sheet is symmetrical to the first central axis, and a distance between the outer lateral edge of the carrying sheet and the first central axis is defined as a first outer diameter;a sheet-like insulating protector having an outer lateral edge symmetrical to the first central axis, wherein the carrying sheet is embedded in the insulating protector; an annular segment defining a second central axis, wherein an outer lateral edge of the annular segment is symmetrical to the second central axis, and a distance between the outer lateral edge of the annular segment and the second central axis is defined as a second outer diameter; the annular segment includes two end portions arranged adjacent to each other and spaced apart from each other; and', 'two extending segments respectively extending from the two end portions toward the second central axis,', 'wherein the second outer diameter is smaller than the first outer diameter, and the second central axis and the first central axis have an ...
