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。

Abstract:

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 decoupled port for the use of T-shaped ground plane.The simulation 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.

Key words: tri band antenna;MIMO;decouple
