System for wireless charging of a plurality of devices
First Claim
1. A master unit for wirelessly charging a plurality of slave devices, said master unit comprising:
- a plurality of radio frequency integrated circuit (RFIC) modules, each of said plurality of RFIC modules being associated with a unique or a shared antenna array;
said master unit having at least three charging modes, at least two of said three charging modes comprising a multi-beam mode and a customized beam pattern mode;
said master unit using each respective one of said unique or said shared antenna array associated with each of said plurality of RFIC modules to form separate beams from each of said plurality of RFIC modules in said multi-beam mode;
said master unit using a customized combination of antennas in selected ones of said plurality of RFIC modules to form a customized beam pattern in said customized beam pattern mode.

Abstract
A master unit for wirelessly charging a slave device includes a plurality of radio frequency integrated circuit (RFIC) modules, each of the plurality of RFIC modules having an antenna array. The master unit is configured to select one of a single beam mode by using all or substantially all antenna arrays in the plurality of RFIC modules, a multi-beam mode by using each respective antenna array in each of the RFIC modules to form a separate beam from each RFIC module, and a customized beam pattern mode by using a customized combination of antennas in selected ones of the plurality of RFIC modules. The master unit is configured to dynamically select from one of the single beam mode, the multi-beam mode, and the customized beam pattern mode based on a location of the slave device relative to the master unit.
