Multi-Chip Antenna Array Layout for Large Virtual MIMO Apertures

The patent divides the MIMO antenna array into multiple separate chips, each containing a subset of antenna elements. This segmentation allows each chip to be manufactured independently with standardized transceiver-integrated antenna designs, avoiding the complexity of integrating all antenna elements on a single large substrate while maintaining the virtual array's spatial resolution capabilities through distributed antenna placement.

The patent transitions from a two-dimensional planar integration approach to a three-dimensional distributed architecture where multiple chips are stacked or arranged in space. This allows the virtual antenna array to achieve a large effective aperture by utilizing the third dimension (vertical stacking or spatial distribution) rather than expanding the substrate area horizontally, thereby maintaining high spatial resolution while minimizing the footprint of individual chips.

The patent segments the system into multiple standardized chips that can be manufactured using conventional fabrication processes. Each chip integrates a manageable number of antenna elements with their corresponding transceivers, allowing for standardized manufacturing without requiring advanced substrates or complex packaging techniques. This segmentation enables mass production of individual chips that can then be assembled into larger MIMO arrays using simpler interconnection methods.
