Abstract
A chip antenna includes: a first dielectric layer; a second dielectric layer upwardly spaced apart from the first dielectric layer; a patch antenna pattern disposed on the second dielectric layer; a feed via extending through the first dielectric layer; a feed pattern disposed between the first and second dielectric layers, electrically connected to the feed via, and spaced apart from the patch antenna pattern; and an adhesive layer adhered to the first and second dielectric layers. The adhesive layer includes a cavity surrounding the feed pattern between the first and second dielectric layers and; and a vent disposed between the cavity and an external side surface of the adhesive layer.
