Abstract
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 radius. 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 radius that is smaller than the first outer radius. The second central axis and the first central axis have an offset distance there-between that is larger than zero.
