一种适用于MIMO系统的宽带小型化天线

摘要

A compact and wideband antenna element for MIMO system was proposed. Because of this single-plate structure, the antenna owned simple structure and small in size. Using the elliptical antenna slot form and the different feeder adopted in two ports for ensuring a better isolation degree, the isolation of dual ports is less than -25 dB in bandwidth range, and the -10 dB bandwidth of 570 MHz can be achieved for the antenna element, while a compact and wideband antenna element for MIMO system is obtained.%研究了一种适用于MIMO系统的宽带小型化天线单元.天线采用单层介质板结构,椭圆天线槽形式,两端口采用不同馈电方式.该天线单元结构简单,厚度小,利于与移动端设备共形.天线单元的-10 dB带宽可达到570 MHz,带宽范围内两极化端口隔离度优于-25 dB.
