ABSTRACT

The integration of extra wireless services in the limited size of mobile devices is a very challenging task. In this context, the antenna array presents the best choice to meet these requirements. This research demonstrates a reconfigurable antenna array system proposed for future 5G applications. The characteristics of the proposed structure are examined while using electromagnetic modeling. The mathematical formulation reposes on combining the moment method and generalized equivalent circuit’s methods (MoM-GEC), and the deduced electromagnetic equations allow the computation of the input impedance $Z_{in}$, the reflection parameter $S_{11}$ and the current and electric field distributions. Software simulations prove good agreement with MoM-GEC results. The obtained results offer the possibility to generate various modes governed by a decision tree. Thus, these modes are related to different resonant frequencies suitable for 5G mobile communications with a large bandwidth reaching 560 MHz.

摘要

在有限尺寸的移动设备中集成额外的无线服务是一项非常具有挑战性的任务。在这种情况下，天线阵列是满足这些要求的最佳选择。这项研究展示了为未来 5G 应用提出的可重构天线阵列系统。在使用电磁建模的同时检查了所提出结构的特性。数学公式依赖于矩量法和广义等效电路法 (MoM-GEC) 的结合，推导出的电磁方程允许计算输入阻抗$Z_{\mathrm{一世}n}$，反射参数 ${秒}_{11}$以及电流和电场分布。软件模拟证明与 MoM-GEC 结果非常吻合。获得的结果提供了生成由决策树控制的各种模式的可能性。因此，这些模式与适用于560 MHz大带宽的5G移动通信的不同谐振频率有关。
