摘　　要：提出了一种用于MIMO系统基站的寄生振子开关八木分集天线.采用寄生振子开关八木天线阵列组成基站分集天线系统.该天线系统充分利用基站空间,在Z向进行组阵以获取阵列增益,在水平面则利用天线方向图的可重构性来进行方向图分集.通过MIMO通信平台的外场测试,得到了多天线系统的误码率的实验数据,说明了该基站天线的确具有提高信道容量、降低误码率的作用.A switched parasitic yagi-uda diversity antenna for MIMO base station is presented. This diversity antenna system is composed of switched parasitic yagi-uda antennas and makes full use of the base station space. It contains antenna array along Z- direction to achieve array gain while uses the reconfigurable radiation pattern to get pattern diversity in the azimuth plane. Using it in the experimental MIMO system shows that this diversity antenna system can increase channel capacity and decrease BElt of the communication system.
