Description
Summary:In this paper, optimization of a miniaturized multiple-inputs multiple-outputs (MIMO) antenna was performed. This antenna was composed of a T-shape radiating element with stub and reduced ground plane and a compact size of 25 mm * 25 mm * 1.6 mm. The behavior of antenna was evaluated in terms of return loss (S-parameter < -10 dB), electromagnetic interference (EMI), and operation frequency. The antenna design is applicable to many applications. A [2.sup.K] factorial design combined with a genetic algorithm (GA) optimization technique were used to identify the key design parameters responsible for affecting the performance quality of the antenna. Optimization of the antenna design for EMI reduction was utilized, and the optimal design showed enhanced bandwidth of the antenna and reduced power consumption. Keywords: factorial design of experiment; genetic algorithm optimization; return loss; electromagnetic interference; multiple-input multiple-output (MIMO)
