INVESTIGATION OF GENERAL WIRE ANTENNAS

Abstract

Integral equations for the current distribution on an arbitrary wire antenna have been programmed for a digital computer. The resulting computer program will calculate the current distribution, the input impedance, and the radiation pattern of a wire antenna of arbitrary geometry. Considered as a transmitting antenna, the antenna is excited by electromotive forces applied in any number of gaps along the wires. The program developed will permit these gaps to be connected by an arbitrary non-radiating network, and it will take into account resistive and reactive loading along the wires. The program will also treat the antenna as a receiving antenna, if desired, and then uses a distant dipole as the source of the induced current distribution. The numerical integral equation method used is essentially an exact method. The principal errors in the calculations arise in the numerical integration of the integrals in the integral equations, and these errors can be controlled. It is usually quite easy to obtain accuracies far better than normal measurement accuracies, and at a much lower cost.
