Abstract: An antenna structure includes a first substrate and a second substrate. There is a dielectric layer between the first substrate and the second substrate. The first substrate includes a first dielectric substrate, and a radiation patch and a micro-strip arranged on the first dielectric substrate. The radiation patch and the micro-strip are on one side of the first dielectric substrate away from the second substrate. Orthographic projections of the micro-strip and the radiation patch on the first dielectric substrate do not overlap. The radiation patch has at least one first slot away from the micro-strip. The second substrate includes a second dielectric substrate, a feed structure arranged on one side of the second dielectric substrate close to the first substrate, and a ground layer arranged on one side of the second dielectric substrate away from the first substrate. The feed structure is electrically connected to the micro-strip.
