1. An antenna module comprising:
a first substrate and a second substrate that have different normal directions;
a number m1 of first radiating elements disposed in a first direction at the first substrate; and
a number n1 of second radiating elements disposed in the first direction at the second substrate, wherein
the first radiating elements disposed in the first direction are more than the second radiating elements disposed in the first direction (m1>n1),
a measurement perpendicular to the first direction of the second substrate is shorter than a measurement perpendicular to the first direction of the first substrate,
a distance from a second radiating element closest to a first end portion in the first direction of the second substrate to the first end portion is longer than a distance from a first radiating element closest to a second end portion in the first direction of the first substrate to the second end portion, and
the first radiating elements and the second radiating elements are configured to emit a radio wave in a frequency band,
wherein the antenna module further includes:
a number m2 of third radiating elements disposed in the first direction at the first substrate, the third radiating elements being configured to emit a radio wave in a second frequency band higher than the first frequency band; and
a number n2 of fourth radiating elements disposed in the first direction at the second substrate, the fourth radiating elements being configured to emit a radio wave in the second frequency band.
