1. An antenna device, comprising:
a first dielectric layer;
a second dielectric layer disposed above the first dielectric layer;
a third dielectric layer disposed between the first dielectric layer and the second dielectric layer;
a feed via configured to penetrate the first dielectric layer;
a first feed pattern disposed between the first dielectric layer and the third dielectric layer;
a third feed pattern disposed between the second dielectric layer and the third dielectric layer and configured to overlap the first feed pattern; and
a patch antenna pattern disposed on the second dielectric layer and configured to overlap the first feed pattern and the third feed pattern,
wherein a dielectric constant of the third dielectric layer is less than a dielectric constant of the first dielectric layer and a dielectric constant of the second dielectric layer.
