Microcomputer Optimization of Feed Excitation Voltages to Obtain Desired Antenna Radiation Patterns.

Abstract

Recently a computer program, MININEC, has become available that can be used to calculate antenna characteristics, including the actual current distribution on the array elements. This program is generally available and can run on various microcomputers. A design procedure for broadcast array antennas has been developed which uses this computer program to calculate antenna characteristics for a specified array geometry. These results are then used by a separate routine that optimizes the excitation voltages, by gradient search, in order to achieve, as nearly as possible, a specified pattern. Keywords include: antenna, array, MININEC, patterns, design, optimal feed excitation, microcomputer techniques, numerical techniques, method of moments, optimization, and least squares.
