Fig. 5 displays the obtained electromagnetic (EM) full-wave simulation and experimental results. It can be noticed that they are in a good agreement that validates designed WIPT. The measured |S11| values for both frequencies show less than −10 dB which conforms to a perfect impedance matching. Furthermore, the obtained |S21| values are −2.23 dB (433 MHz) and −2 dB (900 MHz) correspond to PTE of 60% and 63%. In addition, the measured −10 dB fractional bandwidth at the frequency dedicated for data transfer is 9 MHz. In general, 3 MHz bandwidth is sufficient to use 15 RBs (resource blocks) according to the 3GPP LTE standard [5]. The obtained bandwidth at 900 MHz is three times greater, implying that more RBs can be arranged. Thus, the realized WIPT has the potential to support high data rate applications.

N2 - The near-field wireless information and power transfer system that can support high data rate applications presented in this paper. It was developed by coupling dual-band resonators (DBRs) oscillating at the practical frequencies of 433 MHz and 900 MHz. In turn, the required DBRs were designed applying the slotted ground plane technique. Furthermore, when two 20×20 mm2 DBRs are separated by 18 mm, the power transfer efficiency was measured to be around 60% for both operating bands. Finally, the obtained bandwidth of 9 MHz at the data transfer band allows allocating several resource blocks.
