The antenna module includes a substrate, an antenna structure, and a bottom structure. Both sides of the substrate are provided with the antenna structure and the bottom structure that are connected. A plurality of projection regions respectively defined by orthogonally projecting a first excitation segment and a second excitation segment of the antenna structure onto the metal cover are partially overlapped with the two cover slots. The first excitation segment and the second excitation segment are connected to each other. The bottom structure has two antenna slots.
