Abstract

The analysis of the resistively loaded dipole antenna radiating in homogeneous dielectric medium is performed directly in the time domain. The problem is formulated by means of the time domain Hallen integral equation. The integral equation is solved by the time domain boundary element procedure which enables space and time discretization to be handled separately. Numerical results for the transient antenna current are presented. 1 Introduction Transient response of a thin wire antenna is of great interest in various applications such as electromagnetic pulse (BMP) simulators design and lightning protection systems (LPS) design. The basic requirement in EMP simulators design is to generate a certain time signal with rise and fall times in the order tens and hundreds of nanoseconds. However, the main inconvenien
