An analysis of the transient fields of linear antennas

Abstract

Theoretical solutions for transient radiation from traveling-wave linear antennas were published recently by Chen (see ibid., vol.30, p.80-3, 1988), but the results have some mistakes, and the methods are tedious. A solution in which each term has obvious physical meaning is obtained here in a simple and direct way. The characteristics of the solutions are discussed and compared with strict numerical results. In the time window, the solutions are of a simple form, and their natures are independent of distance. The transient far-field conditions are obtained directly in the time domain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
