Particle swarm optimisation is one of the many optimisation techniques available and is an evolutionary computation technique inspired by social behaviour of bird flocking or fish schooling. This chapter presents a brief introduction to particle swarm optimisation and, in particular, real number, binary and hybrid particle swarm optimisations along with their application to antenna element design. This chapter also provides examples of antenna designs using particle swarm optimisation and comparisons with practical counterparts.
