技術說明

一種多輸入輸出天線，包含：數個天線單元，相鄰二天線單元鏡像對稱地設置於一基板，各天線單元設有一T形饋入體、一輻射體及一接地體，該T形饋入體及該輻射體設於該基板之同一表面，且該T形饋入體形成一直入部及一平頂部，該輻射體之ㄧ端沿該平頂部之一側平行地延伸，且該輻射體係圍繞而成ㄧ矩形區域及一缺口，該接地體設置於該直入部的兩側，且該接地體電性連接該輻射體之另一端；其中，相鄰二天線單元之T形饋入體的直入部並列設置，相鄰二天線單元之接地體相互電性連接。另，揭示一種具有上述天線之系統封裝。 A MIMO antenna is disclosed. The MIMO antenna comprises a plurality of antenna units, with two adjacent antenna units symmetrically mounted on a substrate. Each antenna unit has a T-shape feed, a radiator and a ground. Thus, the T-shape feed and the radiator mounted on the same face of the substrate. The T-shape feed forms a vertical extension portion and a horizontal extension portion. The radiator has an end extending in parallel to the horizontal portion. The radiator extends in a labyrinthine manner to form a rectangular portion and a gap. The ground extends in parallel to the vertical portion on two sides of the vertical portion and is electrically connected to the other end of the radiator. The T-shape feeds of two adjacent antenna units extend in parallel. The grounds of two adjacent antenna units are electrically connected to each other. The invention further discloses a system in package having said antenna.
