LIQUID CRYSTAL-BASED REFLECTIVE METASURFACE, AND REFLECTIVE ARRAY ANTENNA AND ANTENNA DEVICE COMPRISING THE SAME

摘要

A liquid crystal-based reflective metasurface includes a first substrate, a first metal layer formed on a first surface of the first substrate, a second metal layer formed on a second surface of the first substrate, and penetrating the first substrate. A second comprising: a first layer including a first metal via electrically connecting the first metal layer and the second metal layer; layer, and a third layer comprising a third substrate and a third metal layer formed on the first surface of the third substrate, wherein the second metal layer covers the liquid crystal, and the third metal layer is the It covers the bottom of the screen.
