Original Abstract Submitted

An antenna module includes a dielectric substrate, a ground electrode in the dielectric substrate, planar radiating elements, and a peripheral electrode. One radiating element faces the ground electrode. Another radiating element is between the one radiating element and the ground electrode. The peripheral electrode is in a layer of the dielectric substrate between the ground electrode and the other radiating element and electrically connects to the ground electrode. The other radiating element emits a radio wave in a frequency band lower than a frequency band of a radio wave emitted by the one radiating element. The peripheral electrode includes multiple planar electrodes stacked in a first direction in which the one radiating element faces the ground electrode. One planar electrode is in a layer between another planar electrode and the ground electrode. The size of the other planar electrode is less than the size of the one planar electrode.
