Antenna arrangements and routing configurations in large scale integration of antennas with front end chips in a wireless receiver

摘要

A wireless receiver includes a plurality of RF front end chips that receive phase shift signals or amplitude control signals, and output V-combined and H-combined signals. The wireless receiver also includes groups of antennas surrounding each of the plurality of RF front end chips. Each of the plurality of RF front end chips can be surrounded by a group of four antennas in an H-configuration, a group of six antennas in a rectangular- or a hexagonal-configuration, or a group of eight antennas in a rectangular- or an octagonal-configuration. Each of the group of four, six or eight antennas is coupled to a corresponding RF front end chip through antenna feed lines having substantially equal lengths. In another implementation, a pair of RF front end chips uses differential signals to communicate with at least two antennas of a group of antennas surrounding the pair of RF front end chips.
