Abstract:

The primary objective of this effort has been to employ the geometrical theory of diffraction in combination with the moment method to develop a user-oriented computer code to calculate the radiation pattern of wire antennas in the presence of perturbing structures. The work accomplished can be divided into two parts. A theoretical and experimental investigation of the effect of edges on antenna input impedance and current was conducted. Then based on the results of this study, a user-oriented computer code was developed for wire antennas in the presence of a conducting surface bounded by edges, which is positioned over a reflecting surface of infinite extent. Such a configuration can be used to simulate conditions encountered in the design of antennas to meet Air Force requirements. This report describes the above work and concludes with some recommendations to imporve the present code.
