Patent ID: 7728774

Claim:
A radio-frequency integrated circuit chip package with N integrated aperture-coupled patch antennas, N being at least two, said package comprising: a cover portion with N generally planar patches; and a main portion coupled to said cover portion, said main portion in turn comprising: 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 N generally planar patches and substantially parallel thereto; and at least one radio frequency chip coupled to said feed lines and said ground plane; wherein said cover portion and said main portion cooperatively define an antenna cavity, said N generally planar patches being located in said antenna cavity; wherein said main portion further comprises a first substrate layer spaced inwardly from said feed lines, said first substrate layer being formed with a chip-receiving cavity, said radio frequency chip being located in said chip-receiving cavity, and said feed lines are located inwardly of said ground plane; and an island formed within said antenna cavity, thus defining a ring shape of said antenna cavity, said island being substantially opposed to said chip-receiving cavity.
