1. An antenna, comprising:
a first substrate;
a second substrate opposite to the first substrate;
a plurality of radiation units on a side of the first substrate distal to the second substrate; and
a waveguide power division structure between the first substrate and the second substrate, wherein the waveguide power division structure has a waveguide cavity, comprises an input opening and a plurality of output openings, and divides a signal input through the input opening into a plurality of sub-signals, the plurality of sub-signals are output from the plurality of output openings, respectively, and each of the plurality of output openings outputs one of the plurality of sub-signals to at least one of the plurality of radiation units;
wherein the antenna further comprises:
a first conductive layer on a side of the first substrate proximal to the second substrate;
a first electrode on a side of the second substrate proximal to the first substrate; and
a support wall surrounding the first electrode, and a second conductive layer on an inner side of the support wall,
wherein the second conductive layer, the first electrode, and a portion of the first conductive layer corresponding to the first electrode are connected to each other to form the waveguide cavity.
