Abstract
An antenna structure, a manufacturing method thereof, and a communication device are disclosed. The antenna structure includes a first substrate, a second substrate, a dielectric layer, a plurality of first electrodes and a plurality of second electrodes. The dielectric layer is disposed between the first substrate and the second substrate; the plurality of first electrodes are disposed at intervals on a side of the first substrate adjacent to the dielectric layer; the plurality of second electrodes are disposed at intervals on a side of the second substrate adjacent to the dielectric layer; a side of the first substrate facing the second substrate includes a plurality of first recess portions each including a first concaved surface which is dented into the first substrate; the dielectric layer is at least partly disposed in the plurality of first recess portions.
