An antenna is provided, and belongs to the field of communication technology and includes a first dielectric substrate, a first conductive layer, a second dielectric substrate, a second conductive layer, a third dielectric substrate and a conductive third layer which are sequentially stacked. The first conductive layer includes at least one first and second feed lines; the second conductive layer is provided with at least one first and second openings; the third conductive layer includes at least one first radiation part. Orthographic projections of any two of a first opening, a first feed line, a first radiation part corresponding to each on the other first dielectric substrate overlap with other; each an orthographic projection of a first radiation part on the first dielectric substrate intersects with that of each of a corresponding first and second feed lines on the first dielectric substrate.
