摘要
介绍了一种用于WLAN（2.45 GHz,5.15 ～5.85 GHz）和WiMAX（3.50 GHz）3个频段的MIMO天线.该天线包含两个呈直角放置的E型单极子,使其产生3条耦合路径以获得3频特性.两个天线元间放置一个由接地面上凸起的T型隔离单元,降低了天线元间的耦合.仿真结果表明,该天线在其3个工作频段内的回波损耗＜-10 dB,且在工作频带内可获得15 dB的隔离度.
A tri-band printed diversity antenna for 2. 4/3.5/5.2 GHz WLAN/WiMAX operation is proposed. The antenna consists of two orthogonal E-shaped monopoles placed symmetrically with respect to a protruding T- shaped ground plane. The E-shaped monopole can lead to three resonant paths, which can achieve three frequency characteristics. And the antenna can has a highly deeoupled port for the use of T-shaped ground plane. The simula- tion result show that the antenna has good impedance matching with high isolation （S12 〈 - 15 dB in most of the band） for frequencies at the 2. 4 GHz, 3.5 GHz and 5.2 GHz WLAN bands.
