Abstract
An antenna module includes a main substrate and a plurality of sub-array antennas. Each sub-array antenna includes a sub-substrate and a plurality of antenna elements. Each antenna element includes a parasitic element arranged on an upper surface of the sub-substrate, and a feeding element arranged in a layer between the upper surface and a lower surface of the sub-substrate. When a wavelength of a radio wave in free space is λ, a distance between a plane center of the antenna element arranged at a position adjacent to an end surface of the sub-substrate and the end surface is equal to or greater than λ/9, and equal to or less than half a distance (P) between respective centers of two of the antenna elements adjacent to each other in each sub-array antenna.
