1. An antenna apparatus comprising:
a first component layer comprising a plurality of radio frequency integrated circuit chips (RFICs) arranged in a first plane with a first lattice geometry, each of the RFICs comprising beamforming circuitry; and
a second component layer overlaying the first component layer and comprising a plurality of antenna elements arranged in a second plane parallel to the first plane, with a second, different lattice geometry, wherein each of the first and second lattice geometries is a two dimensional geometry, the first lattice geometry is rectangular and the second lattice geometry is non-rectangular, or vice versa, the antenna elements having respective feed points each coupled to an input/output (I/O) pad of one of the RFICs, each said I/O pad being aligned with the feed point coupled thereto along an axis orthogonal to the first and second planes.
