1. A slot antenna, comprising:
a dielectric layer having a first surface and a second surface opposite to each other;
a radiation layer on the first surface of the dielectric layer, and having a plurality of slots therein; and
a first shielding layer on the second surface of the dielectric layer, and electrically connected to the radiation layer;
wherein the slot antenna has a radiation region and a peripheral region surrounding the radiation region;
the dielectric layer comprises a first sub-dielectric layer and a second sub-dielectric layer, a surface of the first sub-dielectric layer distal to the second sub-dielectric layer serves as the first surface of the dielectric layer, and a surface of the second sub-dielectric layer distal to the first sub-dielectric layer serves as the second surface of the dielectric layer; and
the slot antenna further comprises a second shielding layer between the first sub-dielectric layer and the second sub-dielectric layer and within the radiation region.
