1. An array antenna module, comprising:
a feed structure, a phase shift structure, and a radiation structure; the feed structure is connected to the phase shift structure, and the phase shift structure is connected to the radiation structure; the feed structure, the phase shift structure, and the radiation structure are all disposed on a glass substrate,
wherein the glass substrate comprises a first substrate, a second substrate on a side of the first substrate, and a third substrate on a side of the second substrate away from the first substrate; and
the feed structure and the phase shift structure are disposed between the first substrate and the second substrate; the radiation structure is disposed on at least one side of the third substrate,
wherein the phase shift structure comprises a first dielectric layer located between the first substrate and the second substrate, a first conductive layer located on a side of the second substrate close to the first dielectric layer, and a second conductive layer located on a side of the first substrate close to the first dielectric layer; and
an orthographic projection of the second conductive layer on the second substrate partially is overlapped with an orthographic projection of the first conductive layer on the second substrate.
