Original Abstract

The paper is focused on the time domain modeling of antennas by the method of moments. For this modeling, a scheme with weighted Laguerre polynomials is used. For efficient using of this scheme, the scaling factor of the time axis and the number of temporal basis functions has to be determined properly. Otherwise, the scheme is inaccurate and time-consuming. In this paper, several clues how those quantities could be chosen are proposed. Further, there is a discussion how to model feeding ports of symmetrical antennas to get a shorter transient response and so an analysis is less time consuming. Using of proposed approaches is shown on an symmetric strip dipole.
