Abstract
Liquid crystal antenna box, antenna, and method of manufacturing the antenna box are provided. The antenna box includes first baseplate, second baseplate, liquid crystal layer, and insulation layer. The first baseplate includes a first substrate and a first metal layer. The first metal layer includes a ground part and a via between the ground parts. The second baseplate includes a second substrate and a second metal layer. The second metal layer includes a phase shifter and an interval groove between the phase shifters. Surface spacing between the phase shifter, and the insulation layer in the via or a surface of the first substrate close to the second substrate, surface spacing between the ground part, and the insulation layer at the interval groove or a surface of the second substrate close to the first substrate, and surface spacing between the ground part and the phase shifter, are equal.
