在这封信中，我们提出了一个频率可调的多输入多输出天线在704-960 MHz的频率范围和低相关性能的调谐频率。拟议的天线覆盖各种长期演进服务频段：频段17（704-746 MHz）、频段13（746-787 MHz）、频段5（824-894 MHz）和频段8（880-960 MHz）。为了实现主天线的宽带工作，在传统的折叠PIFA结构上采用了倒L形狭缝。该子天线具有多个谐振，通过控制连接到所提出的环形天线的端部的微机电系统的电容，可以从中选择工作频带。通过选择不同的主副天线类型，实现了良好的隔离度和包络相关系数特性。仿真和测量结果都示出了所提出的结构的MIMO能力。© 2015威利期刊公司.微波光学技术快报57：833-838，2015
In this letter, we propose a frequency tunable multiple input multiple output antenna at the frequency ranges of 704–960 MHz and low correlation performance over the tuning frequencies. The proposed antenna covers various long‐term evolution service bands: band17 (704–746 MHz), band13 (746–787 MHz), band5 (824–894 MHz), and band8 (880–960 MHz). To achieve wideband operation for the main antenna, an inverted L‐shaped slit is adopted on the conventional folded PIFA structure. The subantenna has multiple resonance from which on operating bands can be chosen by controlling the capacitance of a microelectromechanical system that is connected to the end of the proposed loop antenna. By choosing different antenna types for the main and subantennas, acceptable isolation characteristic was achieved as well as suitable envelope correlation coefficient characteristics. Both simulated and measured results are shown to illustrate the MIMO capabilities of the proposed structures. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:833–838, 2015
