“…However, such antennas were limited to certain polarisation; therefore, the authors in [26,27] proposed new rectennas with all-polarisation-receiving capability but they suffer from low conversion efficiencies. The efficiency was improved furtherly in [28] but at certain frequency band. Therefore, a double band rectenna design was illustrated for RF energy harvesting in [29].…”

In this study, an investigation is conducted to realise the possibility of organic materials use in radio frequency (RF) electronics for RF‐energy harvesting. Iraqi palm tree remnants mixed with nickel oxide nanoparticles hosted in polyethylene, INP substrates, is proposed for this study. Moreover, a metamaterial (MTM) antenna is printed on the created INP substrate of 0.8 mm thickness using silver nanoparticles conductive ink. The fabricated antenna performances are instigated numerically than validated experimentally in terms of S11 spectra and radiation patterns. It is found that the proposed antenna shows an ultra‐wide band matching bandwidth to cover the frequencies from 2.4 to 10 GHz with bore‐sight gain variation from 2.2 to 3.43 dBi at maximum. The antenna size is compacted to a 32 mm × 24 mm using a fractal‐shaped MTM when mounted on the INP substrate with a relative permittivity ɛr = 3.106−j0.0314 and a relative permeability µr = 1.548−j0.0907. Finally, the maximum obtained voltage from the proposed antenna is found about 2 V at 2.45 GHz and 2.5 V at 5.8 GHz, where, the corresponding measured equivalent isotropic radiated power is about 2.35 W at 2.45 GHz and 6.12 W at 5.8 GHz.

“…In recent years, wireless power transmission (WPT) has become an intriguing solution for contactless powering of low power consuming electronic devices, such as wireless sensors and body area network devices [1]. WPT can be achieved by different approaches such as near-field inductive coupling [2], magnetic resonant coupling [3,4], and microwave power transmission (MPT) [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Comparing with the previous two power transferring approaches, MPT exhibits significant advantages on the ability of energy transfer direction controlling and much longer transmission range.…”

A novel circular polarized rectenna with out-of-band suppression is proposed in this paper. The circular polarization is realized by corner perturbation on a rectangular radiation patch and enhanced by a diagonal slim slot etched at the center of the patch. An open stub connecting to the quarter wavelength impedance transformer is used to suppress out-of-band wave through harmonics notching. The results of simulations and experiments agree very well, which show that the rectenna obtained −19 dB return loss at 2.4 GHz and −15.5 dB, −18.1 dB, and −11.4 dB suppression on second, third, and fourth harmonic frequency bands, respectively. The reflection coefficient in overall out-of-band, up to 10 GHz, is limited up to −3 dB. Integrated with a voltage doubling rectification circuit, the proposed rectenna can obtain 75.5% RF-to-DC conversion efficiency.

“…There have been many efforts on improving the rectenna design by increasing its conversion efficiency as the efficiency reduction is due to the nonlinear behavior of the diodes that cause generation of unwanted harmonic of the fundamental frequency. To overcome this issue, many researchers have proposed adding a low pass filter between the antenna and the rectifying circuit [3][4][5][6][7][8][9] to suppress unwanted harmonics so that the rectenna efficiency would be increased. However, the adaption of the Low Pass Filter (LPF) increases the size and cost of the rectenna and cause isolation loss which limit the practical implementations of the rectenna.…”
