Abstract
A radio frequency identification (RFID) tag that includes an antenna having a spiral form disposed on a major surface of a flexible substrate is described. The RFID tag includes a first terminal disposed at a first end of the antenna and a second terminal disposed at the second end of the antenna. 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.
