摘要
设计了一款应用于手持终端的MIMO双天线系统。天线单元采用了加载寄生支线的方式展宽其工作频带。在天线单元间加载了解耦网络并获得了较高的隔离度。仿真结果表明,该天线系统在700～960MHz及1710～2690MHz的频率范围内,能够满足S11小于-6dB,隔离度优于10dB,并具有良好的辐射性能。
A dual-antenna system is designed for MIMO application in handheld terminals. The antenna unit extends the operating frequency band by loading the parasitic branch line. The decoupling network is loaded between the antenna units, and a high isolation is achieved. The simulation results show that an impedance bandwidth with S11 lower than-6dB over 700-960 MHz and 1710-2690 MHz is obtained, the isolation degree is better than 10 dB, and it has good radiation performance.
