Efficient analysis of wire antennas and scatterers with arbitrary shape

The efficient analysis of wire antennas of arbitrary shape is presented. The exact kernel representations of Green's function are given in place of the thin-wire approximation kernel for the moment method solution of arbitrary wire antennas and scatterers with moderately large radius. The kernel expressions are exactly expanded on the basis of series summations so that the elements of the impedance matrix can be evaluated accurately and quickly. Some numerical examples are performed for validation of the efficiency and accuracy of the proposed method.
