Classification: CPC H | IPC H

Claim 4:
5. An antenna module comprising:
a dielectric substrate having a multilayer structure;
a ground electrode in or on the dielectric substrate;
a plate-like fed element facing the ground electrode, the fed element being at a different layer of the dielectric substrate than the ground electrode;
an unfed element facing the fed element, the unfed element being at a different layer of the dielectric substrate than the ground electrode and the fed element;
a feed line configured to transfer a radio-frequency signal to the fed element; and
a first stub that branches off from the feed line at a first branch point of the feed line, the first stub having a first open end, wherein:
the first stub is between the fed and unfed elements and the ground electrode, and
when the dielectric substrate is viewed in a plan view, the first open end overlaps the fed element or the unfed element.
