Twisted helical antenna for satellite-mobile handset using dynamic multi-objective self-adapting differential evolution algorithm

Abstract

This paper presents a twisted helical antenna, which operates at 2.4GHz and is applied in satellite mobile communications. It is designed using dynamic multi-objective self-adaptive differential evolution (SaDE) algorithm which combines SaDE and dynamically controlling constraint technique. The main reason for adopting dynamic multi-objective SaDE in this paper is that few literatures have used dynamic multi-objective differential evolution (DE) for solving antenna optimization problem so far. A small twisted helical antenna optimized on a perfect ground plane. Results show that while our optimized antenna met the design requirements, its performance is not inferior to the quadriflilar helical antenna as seen in reference. The design shows the capability of evolution algorithm (EA) as an efficient optimization tool for searching globally optimal solutions for antenna design. © 2012 Springer-Verlag.
