摘　　要：该文设计一款双频段MIMO印刷偶极子天线系统,由2个天线单元组成,每个辐射单元由2个不同尺寸的微带开口环组成。通过在地板上开方形栅格,减少了2个天线单元之间的耦合,提高天线端口间的隔离度,在2个工作频段内隔离度均高于25 dB。A dual-band MIMO printed dipole antenna system is designed in this paper,which is composed of two antenna elements,each of which is composed of two microstrip open rings of different sizes.By opening a square grid on the floor,the coupling between the two antenna elements is reduced,and the isolation between the antenna ports is improved,which is higher than 25 dB in the two working frequency bands.

关 键 词：多输入多输出天线 隔离度 双频段 结构设计 辐射方向
