Abstract
An antenna unit is provided. The antenna unit includes a first substrate, a first conductive layer, a second conductive layer, a plurality of conductive vias, a feed conductor and a patch. The first substrate includes a first surface and a second surface, wherein the first surface is opposite to the second surface. The first conductive layer is disposed on the first surface. The second conductive layer is disposed on the second surface, wherein an opening is formed on the second conductive layer, and the opening has an opening edge. The conductive vias are formed in the first substrate and connect the first conductive layer to the second conductive layer, wherein the conductive vias surround the opening to define a cavity. The feed conductor extends above the opening to feed a wireless signal to the antenna unit. The patch is disposed above the opening and is separated from the feed conductor.
