“…After normalizing the amplitude to 1 (deciding by B), the dc component will be exclusively the remaining terms: y dc = 0.50k 2 + 0.37k 4 (6) As expected, Eq. (6) shows that to maximize the harvested power, the diode must operate in the square-law region where k 2 is the maximum.…”

This paper presents a multi-sections broad-band radio-frequency (RF) to direct-current (dc) power rectifier for pulsed signal transfer. The power transfer using a pulse allows to use a signal with low power spectral density. The optimal distributed configuration with critical parameters is studied to enhance the efficiency over broadband frequency and wide power range. A five-stage distributed RF-dc converter arrangement with micro-strip transmission line ensures the power harvesting from 100 MHz to 11 GHz. The designed and fabricated circuit is characterized at multi-frequencies of ultra-wide band (UWB). The distributed harvester significantly improves the detected voltage over a wide bandwidth compared to conventional RF detectors. The achieved efficiency with optimized parameters is 48% with five-stage harvester. A maximum dc output of 956 mV is reached at 8 dBm of input power of sinusoidal single tone signal at 1 GHz of frequency. The designed prototype is associated with a square wave signal to show the circuit potential in terms of power transfer. The output voltage can be controlled with input signal level, frequency, as well as the pulse width. For the power transfer circuit, 996 mV of maximum dc output voltage is reached for 1 V of input amplitude at 1 GHz with duty cycle of 50%. The efficiency increases significantly with duty cycle ratio of the input signal. The power harvester associated with a UWB antenna confirms the benefit of using a square wave signal in the case of power harvesting or transfer.

“…The amount of inset l in the element is chosen to match the patch impedance with that of the feed line [19], [20]. The microstrip line feeding is perhaps the simplest and costs the least, especially which can make for a wholly printed structure [21], [22]. After completing the single element geometry, to increase the receiving power level at the input of the rectifier, and to be able to improve the efficiency of the rectifier, the proposed 2 × 2, 2 × 4 and 4 × 4 rectangular patch antenna arrays are simulated and optimized using the high-frequency structure simulator HFSS [23].…”

This paper demonstrates a Ku-band medium and long distance microwave wireless energy transmission system based on the rectifier diode. The transmitting compact Cassegrain antenna with an aperture of 1.5m forms a more centralized and uniform 2m × 2m field zone, which has more than 80% transmission efficiency. According to the distribution of receiving field, the multiple ways synthesizers connected to rectangular patch arrays are designed. And the results predict that the receiving efficiency of the antenna is directly related to the performance of the system, which reaches 50%, not including the possible insert loss. Besides, the Ku-band rectifying circuit is optimized and measured, and the comparing results show that the practical rectifier diode can obtain more than 40% conversion efficiency at the operating frequency of 12.75GHz. Finally, the microwave wireless energy transmission system is designed, and it finally obtains 4% DC-DC conversion efficiency at a distance of 60m, which is likely to be used in unmanned aerial vehicle hovering charging system, robot charging while working, isolated island wireless power supplying and wireless charging of various sensors.

“…In recently reports, various rectennas have been designed, such as slotted monopole rectenna, 6 shorted patch rectenna, 7 reconfigurable rectenna, 8 and meander line rectenna 9 . In these designs, impedance matching networks are a vital part to use standard antennas with 50 Ω impedances to match with rectifying circuits, and eliminate the second harmonics achieving higher conversion efficiency 10 . Thus, impedance matching network inevitably enlarges the dimension of rectenna.…”

In this article, a compact and high-efficiency loop rectenna with matching network elimination for wireless sensor applications at 2.45 GHz is presented. The proposed hollowed-out square loop antenna is designed and directly provides a conjugate matching to a compact voltage-doubler rectifier. The loop rectenna can harvest microwave power without increasing the total size or affecting the performance of a wireless sensor. The experiment results show that the peak microwave-to-dc conversion efficiency of 74% is obtained at 2.45 GHz when the input power is 18 dBm. The dimension of rectenna is 30 × 30 × 1 mm 3 and only with a weight of 0.58 g, which successfully realizes a high power-weight-ratio (PWR). Hence, the proposed rectenna can provide a convenient and practical charging solution for wireless sensors in various applications.
