Description

一种天线系统

技术领域
本发明涉及通信技术领域，尤其涉及一种天线系统。
背景技术
随着无线通信技术发展，为了提升系统容量，提出了多输入多输出(Multiple InputMultiple Output，MIMO)技术，产生了对多列天线的需求。MIMO通过空分复用方式可以实现空间多流传输，提高通信系统容量；MIMO通过分集方式可以提高通信系统的可靠性。MIMO技术通过增加天线数，实现容量的大幅提升，但同时也对天线设计的性能指标PIM、耗材、体积、重量、成本以及成品率都带来了巨大挑战。
在现有的方案中，如图1所示为了能够满足对多列天线的需求，则天线阵列100包括有多个天线单元101，所述天线单元101通过双工器102同时与接收机103和发射机104相连。
采用现有方案在天线数量增多时，会使得天线单元101的耗材、体积、重量和成本等大量增加，成品率降低。同时，接收机103和发射机104之间的隔离度不够，产生互调问题，导致射频指标下降，甚至完全不可用。
