Abstract

In this paper, the transient response of thin‐wire dipoles is investigated using a time‐domain integral‐equation method. First, an antenna system comprising two straight wire dipoles is numerically analyzed using the direct method and the separation method, and is verified by the measurement. The separation method enables us to consider the transmitting antenna and the receiving antenna separately during the antenna‐system design process. Secondly, the transient response of an antenna excited by pulses with different time duration is investigated. The response strongly depends on the time duration of the pulse. Lastly, the directional characteristics are demonstrated by the gain for dipoles and V‐dipoles. The received pulses by antenna systems composed of V‐dipoles are discussed. © 2004 Wiley Periodicals, Inc.

This paper deals with the numerical modelling of arbitrarily shaped curved antennas by marching on in time (MoT) technique. This time domain version of the method of moments (MoM) is particularly suitable for transient analysis and, in this respect, is more e$cient than the frequency domain approach
