A genetic algorithm is applied to optimize the size and location of a sleeve, which reduces parasitic currents on the surface of the feed cable of a mobile handset antenna, so that the influence of the RF cable on the radiation pattern is minimized. The pattern is calculated by the electric‐field integral equation (EFIE) method in each iteration of the genetic algorithm. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 194–196, 2000
