摘　　要：提出一种用于WLAN无线通信系统的紧凑、双频带、高隔离度的多输入多输出(MIMO)天线.天线由2个对称的改善U型开槽来实现双频的PIFA组成.回波损耗带宽(S11≤-10 d B)覆盖WLAN 2.4 GHz、WLAN 5.2 GHz、WLAN 5.8 GHz.天线利用缺陷接地结构提高了2个PIFA间的隔离度,带宽内保持隔离度-15 d B以下.该天线尺寸小、相互耦合程度低且方向图全向性好,完全适合于WLAN终端设备安装使用.In this paper,a design of compact,dual-bandand high-isolation MIMO antenna for WLAN wireless communication system is proposed.The proposed antenna consists of two symmetrical dual-band PIFA,which is achieved using improved U-shaped slot.The impedance bandwidth(S11≤-10 dB)covers WLAN 2.4,WLAN 5.2,WLAN 5.8 bands.The isolation between two PIFAs remains lower than-15 dB(S12=S21≤-15dB)by using defected ground slot method.The proposed antenna is characterized by sma
