本發明係針對WLAN(Wireless Local Area Network)之多輸入多輸出(MIMO)裝置上提升隔離度的方式探討。以對稱式PIFA天線作為雙天線饋入方式,其具有一個介質基板及一多輸入多輸出天線輻射部。該介質基板具有一接地部;接地部與輻射部之間有一訊號作為饋入,輻射部採用對稱式PIFA天線作為輻射元件,並由接地部延伸一機制來減少天線之耦合量,另外,有一寄生元件與接地部延伸機制間隔一距離,此結構可增加隔離度的表現,且該兩者間距亦會引響隔離度。本發明天線之整體尺寸為20×45×1.6 mm3,量測結果皆有良好現。 A high isolation electromagnetic transmitter and receiver is revealed. An isolation portion, a first antenna body and a second antenna body are extended from and formed over a grounding portion. The isolation portion is extended to and formed between the first antenna body and the second antenna body. A parasitic element corresponding to the isolation portion is disposed between the first antenna body and the second antenna body. The isolation portion is T-shaped. The parasitic element is reverse T-shaped and arranged over the grounding portion. The structure is simple and able to be applied to the design of planar printed antennas. The production is easy and the cost is reduced. The volume is minimized to be used in various mini wireless mobile communication devices. No interference occurs even that the first and the second antennas are close due to good isolation.
