PURPOSE: A patch antenna device with a coupling element, an antenna module, and a communication device are provided to implement various radiation patterns by finely controlling an operation property of an antenna with control points. CONSTITUTION: An antenna device(100) is formed with a patch shape. A ground surface(300) faces the antenna device. One or more coupling elements(310,320,330,340) are arranged between the antenna device and the ground surface. The coupling elements are electromagnetically coupled to the antenna device and the ground device and are arranged along one or more sides of the antenna device. |
