การออกแบบสายอากาศไมโครสตริปแฟร็กทัลมินโควาสกี้โดยใช้วิธีเชิงพันธุกรรม

Abstract

This engineering project presents designing technique for microstrip antenna and improves the return loss with transmission property. Minkowski fractal microstrip antenna is designed by using Genetic Algorithm to find the length and width of the patch. The patch structures are designed to operate at 0.7, 2.6, and 26 GHz. which are the 5G band of mobile systems in Thailand. Designing by MATLAB and CST software, results show that S11 parameters are -3.76, -13.07, and -26.55 dB at 0.7, 2.6, and 26 GHz.
