基于轮式装甲车的4单元MIMO天线布局设计

Design of 4-unit MIMO Antenna Layout Based on Wheeled Armored Vehicle

随着通信需求的增加,装甲车通信系统开始朝着多天线、集成化的方向发展,然而有限空间载体上天线数量的增加势必会对通信系统的正常工作造成影响。为此提出了一种轮式装甲车的4单元MIMO天线布局方案以修正天线单元之间的互耦以及天线和装甲车的耦合造成的方向图畸变。利用CST软件进行建模仿真,仿真结果表明该方案可以实现方向图的修正从而达到全向辐射特性。

With the increase of communication requirements,the communication system of armored vehicle begins to develop towards multi-antenna and integration.The increase of the number of antennas on the limited space carrier is bound to affect the normal operation of the communication system.For this reason,a 4-unit MIMO antenna layout scheme for wheeled armored vehicle is proposed to correct the mutual coupling between antenna elements and the pattern distortion caused by the coupling between antenna and armored vehicle.The CST software is used to model and simulate,and the simulation results show that the scheme can correct the pattern to achieve omnidirectional radiation characteristics.
