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.

Information carrier and tag antenna structure thereof

An antenna structure of an RFID reader includes a carrying plate defining four quadrants and an antenna module disposed on the carrying plate. The antenna module includes a feeding antenna and a grounding antenna. The feeding antenna includes a feeding connecting segment, two feeding transmitting segments connected to the feeding connecting segment, and two feeding radiating segments respectively connected to the two feeding transmitting segments. The grounding antenna includes a grounding connecting segment, two grounding transmitting segments connected to the grounding connecting segment, and two grounding radiating segments respectively connected to the two grounding transmitting segments. The feeding connecting segment and the grounding connecting segment are arranged on an intersection point of the four quadrants, the two feeding transmitting segments respectively correspond in position to the two grounding transmitting segments, and the two feeding radiating segments and the grounding radiating segments are respectively arranged in the four quadrants.
