1. An antenna, comprising: a feed unit layer, a phase shifter layer, an amplifying circuit layer between the feed unit layer and the phase shifter layer, and a temperature control unit layer on a side of the amplifying circuit layer; wherein
the amplifying circuit layer is configured to amplify a microwave signal fed from the feed unit layer and transmit the microwave signal to the phase shifter layer;
the phase shifter layer is configured to shift a phase of the microwave signal by a preset phase shift amount;
the temperature control unit layer is configured to adjust a temperature of the amplifying circuit layer to adjust an operating temperature of the antenna;
wherein the temperature control unit layer is in direct contact with the amplifying circuit layer; and
wherein the feed unit layer comprises a first substrate, a plurality of microwave receiving units on the first substrate, and a transmission line power splitting structure on the first substrate;
the transmission line power splitting structure has a plurality of first ports and a plurality of second ports, wherein each of the first ports is correspondingly connected to one of the microwave receiving units, and more than one of the first ports correspond to one of the second ports;
the amplifying circuit layer comprises a plurality of amplifying circuits, and each of the amplifying circuits is correspondingly connected to one of the second ports; and
the temperature control unit layer is between the amplifying circuit layer and the first substrate; wherein a plurality of flow channels are provided in the temperature control unit layer to accommodate a flow of a working medium.
