Abstract
An antenna device is provided. The antenna device includes a first substrate, a multilayer electrode, a second substrate, and a liquid-crystal layer. The multilayer electrode is disposed on the first substrate, and the multilayer electrode includes a first conductive layer, a second conductive layer, and a third conductive layer. The second conductive layer is disposed on the first conductive layer. The third conductive layer is disposed on the second conductive layer. The liquid-crystal layer is disposed between the first substrate and the second substrate. In addition, the third conductive layer includes a first portion that extends beyond the second conductive layer.
