Antenna and method for manufacturing the same, and antenna system

A method for manufacturing an antenna, comprising:

• providing a dielectric layer;
• forming a pattern comprising a reference electrode layer on a second surface of the dielectric layer by a patterning process, wherein an opening is formed in the reference electrode layer;
• and
• forming a pattern comprising a radiation patch on a first surface of the dielectric layer by a patterning process, wherein an orthographic projection of at least a part of a radiation edge of the radiation patch on the first surface is located within an orthographic projection of the opening on the first surface,
• wherein the pattern comprising the reference electrode layer and the pattern comprising the radiation patch are formed so that the reference electrode layer has a middle area and a peripheral area surrounding the middle area, the opening penetrates through at least a part of a boundary line between the middle area and the peripheral area, an orthographic projection of the radiation patch on the first surface covers an orthographic projection of the middle area of the reference electrode layer on the first surface, the reference electrode layer comprises a first hollow out pattern in the middle area and a second hollow out pattern in the peripheral area, and the radiation patch comprises a third hollow out pattern.

An antenna, comprising:

• a dielectric layer having a first surface and a second surface which are oppositely disposed along a thickness direction of the dielectric layer;
• a radiation patch disposed on the first surface of the dielectric layer;
• and
• a reference electrode layer disposed on the second surface of the dielectric layer and having an orthographic projection on the second surface at least partially overlapping an orthographic projection of the radiation patch on the second surface;
• wherein
• the reference electrode layer has an opening penetrating therethrough along a thickness direction of the reference electrode layer, and an orthographic projection of at least a part of a radiation edge of the radiation patch on the first surface is located within an orthographic projection of the opening on the first surface,
• wherein the reference electrode layer and the radiation patch each are circular or oval in profile;
• the reference electrode layer comprises a plurality of seventh metal lines concentrically arranged in circles and a plurality of eighth metal lines radiating from a center of the reference electrode layer to an edge of the reference electrode layer, at least a portion of the eighth metal lines each are disconnected at positions of the seventh metal lines to define the opening;
• and
• the radiation patch comprises a plurality of ninth metal lines concentrically arranged in circles and a plurality of tenth metal lines radiating from a center of the radiation patch to an edge of the radiation patch.
