The purpose of this chapter is to briefly describe different swarm intelligence algorithms and present their application to antenna and wireless communications design problems. This chapter presents results from design cases that include linear antenna array synthesis for null suppression, thinned arrays, patch antenna, and a partial transmit sequence scheme for peak-to-average-power ratio (PAPR) reduction of orthogonal frequency division multiplexing signals.
