    Abstract: A radio-frequency integrated circuit chip package has N integrated aperture-coupled patch antennas, N being at least two, and includes N generally planar patches, and at least one generally planar ground plane. The ground plane is formed with at least N coupling aperture slots therein. N feed lines are spaced inwardly from the ground plane and substantially parallel thereto, and at least one radio-frequency chip is spaced inwardly from the feed lines and coupled to the feed lines and the ground plane. A first substrate layer is formed with the chip located in a chip-receiving cavity. A second substrate layer is interposed be-tween the ground plane and a plane defined by the patch. The patch is formed in a first metal layer, the ground plane in a second metal layer, and the second substrate layer defines an antenna cavity in which the N generally planar patches are located.
