  • Patent number: 12261371
    Abstract: An antenna module includes feed elements each having a flat plate shape and a ground electrode arranged opposite the feed elements. The feed element radiates a radio wave of a first frequency band. The feed element radiates a radio wave of a second frequency band that is higher than the first frequency band. In a plan view of the feed element, the distance from the center of the feed element to an end portion of the ground electrode in a first direction is shorter than or equal to ½ of a free space wavelength of a radio wave radiated from the feed element. A feed point of the feed element is arranged at a location shifted in a second direction from the center of the feed element, and the second direction is different from the first direction.
