| Abstract: | In this article, the antenna partial gain to  ‐factor based on the antenna current optimization is used as figure of merit for antenna design proposing an efficient global hybrid technique that combining very simple optimization (VSO) and Nelder‐Mead (NM) algorithm. To validate the strength of the approach, a set of three antennas operating within different frequency bands of super high frequency, submillimeter, and light spectrum are addressed and optimized. The antennas are analyzed completely using finite difference time domain method. The results showed the strength of the approach of optimizing antenna gain to  ‐factor based on antenna current optimization using the hybrid VSO‐NM algorithm in different frequency bands. Compared to stand‐alone VSO, the hybrid VSO‐NM algorithm showed the ability to reduce the processing time on average by 58.73% in addition to enhancing the search capability by 43%. |
