Abstract: A disposable timing tag is provided, including a thin, flexible planar sheet member having first and second end sections, and a middle section. A printed radio frequency identification (RFID) circuit is disposed on the middle section thereof and includes an integrated circuit chip, and a dipole antenna electrically coupled thereto. The dipoles of antenna extend generally along the longitudinal axis of the sheet member toward the first and second respective end sections thereof. The first and second end sections of the flexible planar member are separated from the middle section by fold lines formed in the surface of the planar member extending across the horizontal axis thereof, and the planar sheet member is folded such that the first and second ends thereof are connected to one another and the planar member forms a substantially D-shaped closed loop.
