Transient fields of linear antenna arrays
Abstract
An approximate analytical method is presented, which allows calculation of the transient field strength of linear antenna arrays. The detailed investigation of a logarithmicperiodic dipole antenna on the base of different degrees of approximation shows the separate influence of the element radii and the transient mutual coupling between neighbouring elements. For a better physical understanding of its transient radiation process the cylindrical linear antenna when excited by a stepfunction with finite rise time is discussed in detail presenting an extension of a recently published approximate version of the Singularity Expansion Method to nonzero centerloading.
