摘要

提出了一种用于下一代移动电话应用的多频段多输入多输出(MIMO)天线。所提出的MIMO天线由两个相同的元件组成,每个元件有三个分支来产生两个频段,一个宽的高频段和一个窄的低频段。仿真结果表明,这两个频段可以覆盖长期演进(LTE)的下频段、DCS1800、PCS1900和UMTS-2100频段、Wibro频段、WLAN系统的2.4 ghz频段以及WiMAX的上频段。通过在为地平面服务的印刷电路板(PCB)上切割狭缝,可以大大增强两个天线元件之间的隔离,以实现两个频段。

A MIMO antenna for mobile applications
A multiband Multiple-Input Multiple-Output (MIMO) antenna for mobile phones applications in the next generation is proposed. The proposed MIMO antenna consists of two identical elements, each having three branches to generate two frequency bands, a wide higher and narrow lower frequency bands. Simulation results show that these two frequency bands can cover the lower band for Long-Term Evolution (LTE), the DCS1800, PCS1900 and UMTS-2100 bands, the Wibro Band, the 2.4-GHz band for the WLAN system and also the upper band for the WiMAX. By cutting a slit on the printed circuit board (PCB) serving the ground plane, a great enhancement of isolation between the two antenna elements can be achieved for the two frequency bands.
