Claim 1:
2. The phase control device according to claim 1, wherein
each three-dimensional unit comprises:
two active metal layers stacked in the first direction, each active metal layer comprising at least one active component;
at least one passive metal layer stacked with the two active metal layers in the first direction to be interposed between the two active metal layers; and
a plurality of dielectric layers stacked in the first direction with the two active metal layers and the at least one passive metal layer, each dielectric layer being interposed between the active metal layer and the passive metal layer adjacent to each other or between the passive metal layers adjacent to each other, and
the control circuit controls at least one active component in one three-dimensional unit to switch the state of the three-dimensional unit.
