In this paper we present the optimal design of wearable four band antenna that is suitable to work in the fifth-generation wireless systems as well as in cellular systems and in unlicensed bands. The design of the antenna relies on a careful study of optimization algorithms that are suitable for antenna design. We have proposed a benchmark problem to compare different optimization algorithms. It is the space of voltage standing wave ratio and the gain of dipole antenna that was identified for wide range of dipole length and radius. Using this pre-calculated data, we have tuned the parameters of optimization routine for optimal performance with our benchmark. After this, we optimized the geometry of four-band wearable antenna. In the optimization process, we used finite-difference time-domain method together with simplified model of human body. The antenna design was assessed with a fabricated prototype.

使用进化算法优化可穿戴多频带天线的设计优化偶极子基准问题

在本文中，我们提出了适用于第五代无线系统以及蜂窝系统和非授权频段的可穿戴四频段天线的优化设计。天线的设计依赖于对适用于天线设计的优化算法的仔细研究。我们提出了一个基准问题来比较不同的优化算法。电压驻波比和偶极天线增益的空间被确定为宽范围的偶极子长度和半径。使用这个预先计算的数据，我们已经调整了优化程序的参数，以获得我们的基准测试的最佳性能。在此之后，我们优化了四频段可穿戴天线的几何形状。在优化过程中，我们使用了有限差分时域方法以及简化的人体模型。
