Among the computer programs for the analysis of wire antenna and conducting plate, designed to run on personal computer, WIPL, NEC2 and Fidelity are compared. WIPL and NEC2 are programs based on the method of moment applied to the electric field integral equation. Fidelity is the FDTD program. A monopole antenna mounted on the square conducting plate is calculated by using these programs. The monopole is fed at its base. The relative error of input impedance calculated by these programs are compared and discussed.
