技術說明

本發明適用於無線通訊裝置中一種提高多輸入輸出天線間隔離度的方法。其結構包括一多輸入輸出天線、一隔離結構、一有機基板及一系統接地面，該多輸入輸出天線、隔離結構和系統接地面皆以印刷電路之方式設置於有機基板上。其技術主要是於多輸入輸出天線間加上一隔離結構來抑制多輸入輸出天線間之訊號耦合來達到改善多輸入輸出天線間隔離度之效果。該隔離結構為於多輸入輸出天線間設計一突出接地面，其上具有一對左右對稱及個別長度小於1/4λ¬0之二開槽孔，由於其隔離結構對稱之故，此多輸入輸出天線會具有高隔離度、相同之輸入阻抗及空間分集輻射之特性。 The present invention is applicable to a way to improve the isolation between the multi input multi output (MIMO) antenna in the wireless communications device. The device includes one MIMO antenna, an isolation structure, an organic substrate and a system ground plane. The MIMO antenna, the isolation structure and the system ground plane are disposed on the organic substrate through the printed circuit technology. The key technology is to add an isolation structure between the MIMO antenna to improve the isolation with the effect of suppressing the signal coupling between the MIMO antenna. The isolation structure is designed on the protruded ground plane between the MIMO antenna, where there is a pair of slits with symmetrical and individual length less than 1/4λ0 characteristics. Due to the symmetrical structure of the isolation structure, the high isolation, the same input impedance of the antenna and spatial diversity characteristics of the radiation can be obtained.
