Dualband Patch Antenna Design Using Binary Grey Wolf Optimizer

Various antenna design problems are discrete-valued. To address these problems, binary-coded algorithms suited for combinatorial optimization problems are required. Grey Wolf Optimizer (GWO) is a recently proposed evolutionary algorithm based on grey wolves' behavior. Although GWO was originally designed for real-valued problems, discrete versions also exist. In this paper, we apply a binary GWO algorithm (bGWO) for arbitrary-shaped dual-band patch antenna design. Computational results demonstrate that bGWO is quite efficient and can be further applied to discrete valued problems in electromagnetics.
