Abstract
A flat-plate MIMO array antenna includes a substrate, a plurality of antenna elements disposed on the substrate, and at least one isolation element interposed between a plurality of antenna elements on the substrate and connected to a ground. Mutual interference between the antenna elements is prevented by the isolation element formed between the antenna elements, thereby preventing the distortion of the radiation pattern. Also, since the isolation element is grounded to the ground surface, the isolation element operates as a parasitic antenna, thereby increasing the output gain.

A flat-plate Multiple Input and Multiple Output (MIMO) array antenna comprising:
- a substrate;
- a plurality of antenna elements disposed on the substrate;
- and
- at least one isolation element interposed between each antenna element of the plurality of antenna elements and connected to a ground,
- wherein the at least one isolation element is U-shaped and comprises a first strip, a second strip and a third strip, and each strip is separately disposed on the substrate.
