Genetic-algorithm optimization of dipole equivalent-circuit models

In this paper, we use a genetic‐algorithm (GA) technique to optimize equivalent‐circuit models of an antenna system. Two broadband equivalent‐circuit models with component values are optimized by use of the genetic algorithm. The first is a conventional RLC network, while the second introduces a new...

Description
Summary:In this paper, we use a genetic‐algorithm (GA) technique to optimize equivalent‐circuit models of an antenna system. Two broadband equivalent‐circuit models with component values are optimized by use of the genetic algorithm. The first is a conventional RLC network, while the second introduces a new technique that makes use of transmission‐line segments as well as lumped components. Both equivalent circuits exhibit good impedance fidelity over a bandwidth exceeding five octaves, including the fundamental through the fourth overtone response. © 2000 John Wiley & Sons, Inc.
