Abstract

Recently, genetic algorithm/method of moments (GA/MoM) technique has been used as an efficient optimization tool for many antenna design problems. In this paper, a GA/MoM code is developed and used for compressing the size of the wideband log-periodic dipole array (LPDA). The numerical simulations prove that the optimized LPDA with compressed dimensions has nearly the same characteristics of the previously published designs. The optimized LPDA is then applied to a Cantor fractal array design and a multiband behavior is obtained successfully.
