The RFID tag may include a pad portion along the length of the antenna between the first and second ends for mounting an integrated circuit. Except for the pad portion, a radius of curvature of the antenna along at least 90 percent of a length of the antenna between the first and second ends is greater than about 0.1 mm and less than about 10 mm.
