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
