A FAST AND ACCURATE TECHNIQUE FOR FSS AND ANTENNA DESIGNS BASED ON THE SOCIAL SPIDER OPTIMIZATION ALGORITHM

摘要

This paper presents a fast, accurate, and multifunctional electromagnetic optimization bioinspired technique that uses the social spider optimization algorithm (SSO). The proposed technique is applied to the design of a frequency selective surface (FSS), with Vicsek fractal patch elements, and an ultra wideband antenna (UWB), consisting of a ring monopole. In the proposed (synthesis) technique, the use of a database or the construction of a neural network is not required. The SSO algorithm communicates via scripts directly with the Ansoft HFSS software tool, enabling a good flexibility in the number of parameters to be optimized and reducing the required computation time. The accuracy and efficiency of the proposed technique is confirmed by comparison with experimental results and with other simulation techniques. (C) 2016 Wiley Periodicals, Inc.
