Table 2.

Recording the duty cycle for varying wireless charging for the cases with varying distances between the Tx and Rx, and with varying input RF power using 5 Tx antennas (first 3 rows for Input power) and 10 Tx antennas (last 3 rows for Input power). The output voltage pulses were in the range of 4.2 to 5.5 V for all cases.
