摘要
针对手机低频高隔离度天线设计要求,研究移动终端四天线系统空间布局、耦合机理及解耦方法,提出一种采用T型地枝组合低频段宽带低互耦的天线设计方法。利用用仿真软件,分析并设计一个可用于5.7英寸手机的低频段高隔离度四天线系统,实验测试数据表明,新设计方法可提升多天线系统性能。
To match the requirements for low frequency and high isolation mobile antennas, the spatial configurations for mobile terminals with four antennas are studied, furthermore,both coupling theory and decoupling techniques are exploited, after this, a MIMO antenna design technique for 5. 7 inches mobile terminal which consists of four antennas with T-shape slots is proposed. Experiments are done to show that the proposed technique works in a better performance.
