Claim 0:
1. An antenna, comprising:
a substrate having a first surface and a second surface oppositely disposed;
a first reference electrode arranged on the first surface of the substrate;
a radiating element arranged on the second surface of the substrate, and feeding directions of a first port and a second port of the radiating element are different;
at least one transmission structure arranged on the second surface of the substrate, and connected to at least one of the first port and the second port of the radiating element; wherein
the transmission structure comprises a signal electrode, a second reference electrode arranged on at least one side of the signal electrode in an extending direction of the signal electrode, and at least one membrane bridge; the signal electrode is configured to feed a microwave signal into the radiating element, is positioned in a space surrounded by the membrane bridge and the substrate, and is insulated from the membrane bridge through an interlayer dielectric layer; an orthographic projection of the membrane bridge on the substrate overlaps with an orthographic projection of the second reference electrode on the substrate.
