| 摘要 |
A MIMO antenna device has a substrate 1 incorporating a first ground plane 2, a symmetric conductive strip 5 having first and second arms 6, 7 each having a proximal portion and a distal portion, a first conductive strip 11 located generally between the distal portions and adjacent to the proximal portions of the first and second arms, a second conductive strip 15 located generally adjacent to the first arm and a third conductive strip 16 located generally adjacent to the second arm. The first to third conductive strips are configured to be unbalanced. The symmetrical conductive strip may be configured to be balanced or the first arm may be unbalanced and the second arm a ground plane. The antenna device may be configured with four or five feed points, and may drive from four up to ten signal ports. The device enables conductive strips to be located in close proximity whilst providing sufficient isolation between the ports. |
