Controlling Radio Frequency (RF) signals through switching technology is of interest to designers of modern wireless platforms such as Advanced Wireless services (AWS) from 2.18 GHz–2.2 GHz, mid-bands of sub-6 GHz 5G (2.5 GHz and 3.5 GHz), and 4G bands around 600 MHz/700 MHz, 1.7 GHz/2.1 GHz/2.3 GHz/2.5 GHz. This is because certain layout efficiencies can be achieved if suitable components are chosen to control these signals. The objective of this paper is to present a new model of an RF switch denoted as a Magnetostatic Responsive Structure (MRS) for achieving reconfigurable operation in 4G/5G antennas. In particular, the ABCD matrices of the MRS are derived from the S-parameter values and shown to be a good model from 100 KHz to 3.5 GHz. Furthermore, an overall agreement between simulations, analytical results, and circuit model values are shown.

适用于4G / 5G（Sub-6 GHz）可重构天线的响应于静磁场线的微米级导电粒子组成的新型结构的表征

现代无线平台的设计人员对通过开关技术控制射频（RF）信号感兴趣，例如2.18 GHz至2.2 GHz的高级无线服务（AWS），低于6 GHz的中频5G（2.5 GHz和3.5 GHz） ，以及大约600 MHz / 700 MHz，1.7 GHz / 2.1 GHz / 2.3 GHz / 2.5 GHz的4G频段。这是因为，如果选择合适的组件来控制这些信号，则可以实现某些布局效率。本文的目的是提出一种称为静磁响应结构（MRS）的RF开关的新模型，以实现4G / 5G天线中的可重构操作。特别是，MRS的ABCD矩阵是从S参数值得出的，并且显示为100 KHz至3.5 GHz的良好模型。此外，还显示了仿真，分析结果和电路模型值之间的总体一致性。
