This chapter is dedicated to bio-inspired computing techniques and their
applications in antennas. The working principles of ANN, ANN Ensemble, GA, PSO,
and BFO are described, and some hybrid bio-inspired computing techniques are also
discussed. The literature survey related to the applications of bio-inspired computing
optimization techniques in antennas is given in this chapter. The limitations of the
existing bio-inspired computing techniques are highlighted. The existing applications
of bio-inspired computing techniques in fractal antennas are also reviewed in this
chapter.
