Document Type and Number:
WIPO Patent Application WO/2022/178800
Kind Code:
A1
Abstract:
Provided in the present invention is an antenna, relating to the technical field of communication. The antenna of the present invention comprises: a substrate having a first surface and a second surface arranged opposite to one another; a first reference electrode arranged on the first surface of the substrate; a radiating element arranged on the second surface of the substrate, the feeding directions of a first port and a second port of the radiating element being different; and at least one transmission structure arranged on the second surface of the substrate, the transmission structure being connected onto at least one of the first port and the second port of the radiating element; the transmission structure comprises: a signal electrode, a second reference electrode arranged on at least one side of the direction of extension of the signal electrode, and at least one membrane bridge; the signal electrode is configured to feed a microwave signal to the radiating element and is positioned in a space enclosed by the membrane bridge and the substrate, and the signal electrode is insulated from the membrane bridge by means of an interlayer dielectric layer; and the orthographic projections of the membrane bridge and the second reference electrode on the substrate overlap.
