This paper presents evolutional design of antennas for passive IC tags used at UHF-band. The shape of wire antennas is optimized using the genetic algorithm (GA) aiming at maximization of feeding power to the IC tag to lengthen the communication distance as well as minimization of the antenna size. The characteristics of the antennas printed on a dielectric substrate are evaluated using the moment method in the optimization processes. Genotypes for GA are introduced to express the shapes of lattice antennas which include loops and floating lines, and spiral antennas. It is shown that optimized antennas satisfy the required condition, and have smaller sizes in comparison with conventional meander antennas.
