An transparent antenna includes a first substrate and a second substrate oppositely arranged; the first substrate includes: a first dielectric layer having a first surface and a second surface oppositely arranged; a reference electrode layer on the first surface; at least one first radiation part on the second surface and having a orthographic projection on the first surface at least partially overlapping an orthographic projection of the reference electrode layer on the first surface; at least one feeding structure on the second surface and feeding the first radiation part; the second substrate includes: a second dielectric layer having a third surface opposite to the second surface and a fourth surface oppositely arranged; at least one second radiation part on the fourth surface, an orthographic projection of each second radiation part on the first surface is within an orthographic projection of one first radiation part on the first surface.
