Also, antenna performance including reflection loss and gain have been optimized during the scale-down process. The proposed antennas are compared with the theoretical limits of small antennas to confirm the optimized performance in a limited space. The smallest possible size of the proposed antenna is 0.0232l0 in length or ka = 0.103. The proposed scaling strategy will be applied to the design of RFID on-chip antennas in the future.en621conference paper
