Millimeter wave array antenna module and mobile terminal

Abstract

A millimeter wave array antenna module and a mobile terminal are provided. The millimeter wave array antenna module includes a dielectric substrate, a radio frequency integrated circuit chip affixed to one side of the dielectric substrate, a plurality of antenna units arranged in an array and disposed on a side of the dielectric substrate facing away from the radio frequency integrated circuit chip, and a feeding network formed in the dielectric substrate. Each antenna unit is electrically connected to the radio frequency integrated circuit chip through the feeding network, and includes a substrate integrated waveguide and a patch antenna. The substrate integrated waveguide has a back cavity and the patch antenna is arranged in the back cavity and affixed to the substrate integrated waveguide.
