Antenna Topology Optimization Based on Angle-modulated Bat Algorithm

Abstract

This paper proposes an angle-modulated bat algorithm (AMBA) for antenna topology optimization. Angle-modulated bat algorithm provides a technique that enables the bat algorithm (BA) developed for continuous problems to operate in binary spaces, which has very fast optimization speed and better search performance. Design results of a compact dual-band monopole antenna are presented, showing that the proposed method outperforms the commonly used binary particle swarm optimization (BPSO) and binary bat algorithm (BBA) in optimization of time.
