1. An antenna module comprising:
a first ground pattern;
a radiation electrode disposed above the first ground pattern in a first direction;
a feed electrode disposed between the first ground pattern and the radiation electrode in the first direction; and
a ground conductor surrounding the radiation electrode and feed electrode when viewed from the first direction,
wherein a planar size of the radiation electrode is smaller than a planar size of the feed electrode,
wherein the ground conductor includes a plurality of through hole conductors arranged so as to surround the radiation electrode and feed electrode when viewed from the first direction and a second ground pattern having an annular shape and connected to the first ground pattern through the plurality of through hole conductors,
wherein the ground conductor further includes a third ground pattern having an annular shape and connected to the first and second ground patterns through the plurality of through hole conductors, and
wherein the third ground pattern is arranged between the first ground pattern and the second ground pattern in the first direction without the third ground pattern overlapping the feed electrode in the first direction.
