Numerical optimization of geometry parameters is a critical stage of the design process of compact antennas. It is also challenging because size reduction is constrained by the necessity of fulfilling imposed electrical performance requirements. Furthermore, full‐wave electromagnetic (EM) analysis needs to be used for reliable performance evaluation of the antenna structure, which is computationally...
In this paper, we consider size reduction of antenna structures by means of simulation-based numerical optimization. We investigate the properties of explicit formulation with the footprint area minimization being a primary design objective and a penalty function introduced to control reflection characteristic of the antenna at hand. A novel formulation with adaptive adjustment of the maximum acceptable...
