This paper discusses a review of frequency reconfigurability through switches for 5G applications. A new switching technique (varying values of lumped parameters) for frequency reconfiguration is analysed and validated by investigation a difference between a simple (non-reconfigurable) and a reconfigurable antenna for 60 GHz resonant frequency. Different switching techniques for frequency Reconfigurable Antenna (RA) and formulations for the parameters of Microstrip Patch Antenna and slot insertion. Generic interconnections of switches for antenna array is addressed for RA design. important aspect of this paper is that these techniques have been discussed for the frequency switching of Reconfigurable microstrip antennas designed for 5G applications i.e. their frequency of operation is in millimetre-wave range (>6GHz).

本文讨论了通过开关对 5G 应用进行频率可重构性的回顾。通过研究简单（不可重构）天线和 60 GHz 谐振频率的可重构天线之间的差异，分析并验证了一种用于频率重构的新开关技术（集总参数的变化值）。频率可重构天线 (RA) 的不同开关技术以及微带贴片天线和插槽插入参数的公式。天线阵列开关的通用互连是针对 RA 设计的。本文的一个重要方面是讨论了这些技术，用于为 5G 应用设计的可重构微带天线的频率切换，即它们的工作频率在毫米波范围 (>6GHz) 内。
