“…Wireless energy transfer (WET) experiments have been conducted widely by some researchers. Various applications for this technology have been implemented, such as for energy harvesting [12]- [16] communication [17], charging devices [18], [19], medical [20]- [24], and off-body radio link [25]. Those applications adopted one of the five techniques of WET technology, namely coupling inductive, coupling capacitive, coupling magnetic, coupling magnetic resonant, and microwave radiation [26].…”

“…The range of frequency in the experiment was about 400 to 489 MHz, and the standing wave ratio (SWR) was 1.2. The best efficiency occurred when the rotation angle of the directional antenna was 60° at 0.36% [12]. The following research used the same method to cover 10 cm in distances, with an efficiency of 0.00116% and a size of 1.44 cm 3 [14].…”

This paper aims to design a receiving antenna for harvesting energy using the wireless energy transfer method based on the ultra-high frequency (UHF) band. The study was conducted by comparing four types of the receiving antenna design. A mathematical and experimental analysis has been done to evaluate the performance of the designed antennas. A Yagi-Uda antenna is utilized as the transmitter. The results show that the zig-zag type antenna has the best performance. It can receive electromagnetic energy from a transmitter with maximum efficiency is 0.1% for the receiving antenna volume of 0.34 cm<sup>3</sup>. The proposed method can meet the energy necessity of an implant device with a charging time of approximately 21.61 hours for the 700 mAh rechargeable battery capacity. As our preliminary conclusion, based on our results, this proposed method can be used as a reference for the practice in the WET field and the medical and restricted areas in the electromagnetic energy harvesting case.
