Patent ID: 7692590

Claim:
A radio-frequency integrated circuit chip package with at least one integrated aperture-coupled patch antenna, said package comprising: at least one generally planar patch; at least one generally planar ground plane spaced inwardly from said generally planar patch and substantially parallel thereto, said ground plane being formed with at least one coupling aperture slot therein, said slot being substantially opposed to said patch; at least one feed line spaced inwardly from said ground plane and substantially parallel thereto; at least one radio frequency chip spaced inwardly from said feed line and coupled to said feed line and said ground plane; a first substrate layer spaced inwardly from said feed line, said first substrate layer being formed with a chip-receiving cavity, said chip being located in said chip-receiving cavity; a second substrate layer interposed in a region between said ground plane and a plane defined by said patch; a third substrate layer interposed in a region between said ground plane and said feed line; a covering substrate layer located outwardly from said second substrate layer, said covering substrate layer having an inner surface; and a reflector spaced inwardly from said third substrate layer and generally opposed to said coupling aperture slot; wherein: said patch is formed in a first metal layer on said inner surface of said covering substrate layer; said ground plane is formed in a second metal layer; said feed line is formed in a third metal layer; and said second substrate layer and said covering substrate layer cooperatively define an antenna cavity, said at least one generally planar patch being located in said antenna cavity.
