| Abstract | − In the present work, a Galerkin’s electric field integral equation (EFIE) solution is applied to get the current flowing on a conducting surface of arbitrary shape when excited by a gap generator as well as when illuminated by an incident plane wave. The main objective of this work is to get a fast, accurate and efficient computer algorithm that optimizes the use of computer resources and reduces the computational time and to accurately evaluate the input impedance of conducting surface antennas. The singular integrals arising in such a Galerkin’s formulation are accurately evaluated and obtained as analytic expressions. An efficient method is described for accurate evaluation of the input impedance for antennas of arbitrarily-shaped conducting surface. The efficiency of the applied Galerkin’s algorithm is examined by calculating the input impedance of well known antennas of conducting surfaces such as the strip-dipole, bow-tie and planar equiangular spiral antennas. To investigate the accuracy of the applied technique the results concerning these antennas are presented and compared with some published results. |
