Wireless charging system
First Claim
1. A master unit for wirelessly charging at least one slave device, said master unit comprising:
- a plurality of radio frequency integrated circuit (RFIC) modules, each of said plurality of RFIC modules including an antenna array;
said master unit having at least three charging modes comprising a single beam mode, a multi-beam mode, and a customized beam pattern mode;
said master unit using all or substantially all antenna arrays in said plurality of RFIC modules to form a single beam in said single beam mode;
said master unit using each respective antenna array in 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.
