Abstract
An antenna device according to embodiment includes: a first dielectric layer; a second dielectric layer disposed on the first dielectric layer; a third dielectric layer disposed on the second dielectric layer; a first antenna including a first feed via passing through the first dielectric layer and a first antenna patch disposed in a first surface of the first dielectric layer; and a second antenna including a second feed via passing through the first dielectric layer and a second antenna patch disposed in the first surface of the first dielectric layer, wherein a dielectric constant of the second dielectric layer is lower than a dielectric constant of the first dielectric layer and a dielectric constant of the third dielectric layer, and the second dielectric layer has a cavity overlapping the second antenna patch.
