Numerical Electromagnetics Code (NEC)-Reflector Antenna Code. Part I. User's Manual.

Abstract

This report provides the necessary information to run a Fortran IV computer code by which the near field or the far field patterns of a typical Navy reflector antenna can be calculated. This code was developed as part of a larger effort to develop computer models for simulating antennas at UHF and above frequencies in a complex ship environment. The theoretical approach for computing the fields of the general reflector is based on a combination of the Geometrical Theory of Diffraction (GTD) and Aperture Integration (AI) techniques. Various examples are presented to illustrate the versatility of the codes as well as its operation. (Author)
