Abstract
A dual polarization antenna device for creating a dual band function, includes: a first dielectric body, a patch layer, a first phase difference changing structure, a second dielectric body, a common metal layer, a ground layer, a second phase difference changing structure, a first antenna feed pin, and a second antenna feed pin. The first dielectric body, the patch layer, the first phase difference changing structure, the common metal layer, and the first antenna feed pin are combined together to form an upper polarization antenna structure. The second dielectric body, the common metal layer, the second phase difference changing structure, and the ground layer are combined together to form a lower polarization antenna structure. Therefore, the upper polarization antenna structure and the lower polarization antenna structure are combined to create both the dual polarization and the dual band functions.
