The sparse matrix for analyzing linear antennas is obtained based on the MEI method. The surface current densities and vector potentials are linearly coupled in a finite‐difference formulation, in which the coefficients are determined by the MEI method. In comparison with that of the MoM method, the impedance matrix obtained is highly sparse; hence, there are great savings of computer storage and computation time. This kind of technique is expected to be applied in large structures. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 88–90, 1999.
