Abstract

See full text

A phase-shift unit includes: a first substrate and a second substrate provided opposite to each other; a medium layer provided between the first substrate and the second substrate; a microstrip line disposed at a side of the second substrate facing towards the first substrate; and a grounding layer provided at a side of the first substrate facing towards the second substrate and formed with a via hole; wherein a projection of the via hole onto the second substrate and a projection of the microstrip line onto the second substrate have an overlapped area therebetween; and wherein the via hole is configured to feed a phase-shifted microwave signal out of the phase-shift unit, or feed a microwave signal into the phase-shift unit such that the microwave signal is phase-shifted.
