Abstract
A RFID tag to be attached to an object to identify the object or a characteristic or feature thereof from data stored in the tag accessible by a RFID reader includes a relatively flat structure having a small aperture antenna positioned on or proximate the tag in the form of a polygon having electrically conductive sides. The flat structure, which may be fabricated as a sticker or label, incorporates a small aperture antenna, such as a slot antenna, in the form of a polygon having electrically conductive sides. The polygon may be triangular, rectangular, square, elliptical, circular, or other polygonal figure depending on number of its plurality of sides. A constitutes the aperture of the antenna. An integrated circuit chip containing the electronics of the tag is secured to the flat structure within the boundary of the aperture constituting the central open portion within the polygon, and substantially equidistant from a pair of opposite sides of the polygon, with a pair of conductive impedance matching elements of substantially equal length confronting each other in the aperture from the opposite sides. Methods of use are disclosed.
