- Abstract
- This paper presents near field beam steering arrays for wireless power transfer. Two types of near field beam steering arrays are introduced. One is two-dimensional array; the near field power is steered to a specific position of a receiver whose separation is 50 cm from the array at the frequency of 6.78MHz. The other is three-dimensional array which is composed of mode reconfigurable resonators insensitive to its alignment; the WPT efficiency in the azimuthal plane is measured at the transmitting distance of 20 cm at the frequency of 13.56MHz. Near field beam steering is achieved by controlling each capacitance of array resonator in both cases. The experimental results agree with the theoretical results.
