Patent ID: 7696930

Claim:
A radio-frequency integrated circuit chip package with N integrated aperture-coupled patch antennas, N being at least two, said package comprising: N generally planar patches; at least one generally planar ground plane spaced inwardly from said N generally planar patches and substantially parallel thereto, said ground plane being formed with at least N coupling aperture slots therein, said slots being substantially opposed to said patches; N feed lines spaced inwardly from said ground plane and substantially parallel thereto; at least one radio frequency chip spaced inwardly from said feed lines and coupled to said feed lines and said ground plane; a first substrate layer spaced inwardly from said feed lines, said first substrate layer being formed with a chip-receiving cavity, said chip being located in said chip-receiving cavity; and a second substrate layer interposed in a region between said ground plane and a plane defined by said patch, wherein: said patch is formed in a first metal layer; said ground plane is formed in a second metal layer; and said second substrate layer defines an antenna cavity, said N generally planar patches being located in said antenna cavity.
