Abstract
Disclosed are a dual-polarization cavity-backed antenna, a package module and an array package module. The antenna includes a substrate, a magnetic current feeding structure, an electric current feeding structure, and a cavity-backed structure that is arranged between two surfaces of the substrate. The magnetic current feeding structure and the electric current feeding structure transfer energy into the cavity-backed structure, respectively radiating the orthogonally polarized electromagnetic wave. The electric field direction of the first electromagnetic wave and the magnetic field direction of the second electromagnetic wave occur on the same plane. The package module includes the dual-polarization cavity-backed antenna, a radio frequency control chip, and a control circuit unit. The array package module includes a plurality of the dual-polarization cavity-backed antennas, a radio frequency control unit including a single RF chip or chip set, and a control circuit unit.
