Abstract

This paper presents the use of the multiple sweep method of moments (MSMM) in the design of electrically large wide-band antennas. The MSMM is an O(N²) recursive method for solving the large matrix equations which arise in the method of moments (MM) analysis of electrically large bodies. Although the MSMM is a frequency-domain solution, it has a time-domain interpretation. The main point of this paper is to show that this time-domain interpretation can be used to identify the location and magnitude of points of current reflections, thus making the MSMM a useful tool for the analysis and design of wide-band antennas. The method is applied to the three-dimensional (3-D) problems of a long dipole antenna with a reactive load in the center of each arm and a TEM horn antenna with a bend
