1. An antenna, comprising a first dielectric substrate, a first conductive layer, a second dielectric substrate, a second conductive layer, a third dielectric substrate and a third conductive layer which are sequentially stacked;
wherein the first conductive layer comprises at least one first feed line and at least one second feed line;
the second conductive layer is provided with at least one first opening and at least one second opening therein; and
the third conductive layer comprises at least one first radiation part;
wherein orthographic projections of any two of the first opening, the first feed line, the first radiation part corresponding to each other on the first dielectric substrate overlap with each other; and orthographic projections of any two of the second opening, the second feed line, the first radiation part corresponding to each other on the first dielectric substrate overlap with each other; and
an outline of an orthographic projection of the first radiation part on the first dielectric substrate intersects with an orthographic projection of each of the corresponding first feed line and the corresponding second feed line on the first dielectric substrate, and the orthographic projection of each of the first feed line and the second feed line on the first dielectric substrate extends into the orthographic projection of the first radiation part on the first dielectric substrate; and the at least one first feed line and the at least one second feed line have different extending directions;
wherein the first feed line comprises a first feed line sub-segment and a second feed line sub-segment connected in a T shape;
the second feed line comprises a third feed line sub-segment and a fourth feed line sub-segment connected in a T shape; and
wherein the first feed line further comprises a first branch;
the second feed line also comprises a second branch;
the first branch is connected to one end of a corresponding first feed line sub-segment;
an extending direction of the first branch intersects with an extending direction of the first feed line sub-segment;
an extending direction of the second branch intersects with an extending direction of a corresponding third feed line sub-segment; and
orthographic projections of the first branch and the second branch on the first dielectric substrate are both covered by the orthographic projection of a corresponding first radiation part on the first dielectric substrate.
