1. A wireless power transmission device, the device comprising:

  • a driver circuit configured to generate first and second driver signals;

    a first antenna array of antenna coils configured to generate a first wireless field based on the first driver signal powering the first antenna array such that adjacent antenna coils of the first antenna array are powered with opposite polarities; and

    a second antenna array of antenna coils partially overlapping the first antenna array, the second antenna array configured to generate a second wireless field orthogonal to the first wireless field, the second wireless field generated based on the second driver signal powering the second antenna array such that adjacent antenna coils of the second antenna array are powered with opposite polarities.
