“…The spatial output voltage distribution of the rectenna primarily depends on the radiation pattern of the antenna itself. Van Hoang et al [18] have distributed a 3D voltage pattern measurement of a rectenna and then compared it with the 3D radiation pattern from the same antenna used in the rectenna.…”

Ambient radiofrequency (RF) energy scavenging has been recently addressed with a wide range of studies to provide alternative powering for low-power applications. However, due to the low power level of the ambient electromagnetic field, the efficiency of the latter systems is still below expectations. Multipath in the environment may be considered and antenna diversity is then a solution for quasi-omnidirectional RF reception to reach a higher probability of receiving energy in a realistic situation. A 3D flexible antenna diversity, which can be integrated into the rectangular packaging, is proposed in order to take advantage of system packaging form. The angle and polarization diversity antenna was designed on flexible substrate in order to achieve the flexibility and low-cost. This design overcomes the low performance of the substrate while maintaining a compact, high isolation, and good radiation efficiency of the antenna. An indoor experimental setup was carried out to compare different rectenna configurations. The measurement results validate the principle and demonstrate the performance of the 3D flexible diversity system. The probability measurements were carried out under precise conditions in indoor scenarios and the results in comparison with statistic models confirmed the performance of the system in such low power conditions.

“…For the measurement of diversity, two rectennas presented in our previous work [5][6] which consists of a PIFA of 2.0 dB of gain, an input matching circuit, an input band-pass filter, an HSMS-2860 Schottky diode and an output low-pass filter were used. The Printed Circuit Board (PCB) layout of the proposed rectenna is shown in Fig.…”

“…An RF-to-DC conversion efficiency of 60% is achievable over the input power range of 5-30 mW and an output DC voltage of 1.0 V was harvested at a power density of 0.51 mW/cm 2 . More information concerning the RF-to-DC conversion efficiency and output DC voltage as the function of the incident RF power density of this rectenna were detailed in [6].…”

Interest in wireless power transmission (WPT) systems has increased remarkably in recent years thanks to their unlimited applications in wireless sensor networks, energy harvesting systems, RFIDs and so on. The key element on the receiving side of a WPT system is the rectenna (rectifier + antenna) which receives electromagnetic power and converts it into electric power. This paper investigates space diversity technique for a WPT system operating in multipath environments. First, a reference rectenna operating at 2.45 GHz is presented. Then, the measurement setup is described with the sleeve dipole transmitting antenna, the movable rectenna receiving system and the configuration of the environment. The results demonstrate that by using two rectennas separated by an optimized distance based on space diversity technique, the phenomenon of deep fading in real environment is considerably mitigated and the DC output signal is rather stable over the position range of the receiver.

“…The first way, high gain and high power capacity antenna arrays are utilized as the receiving antenna of RF energy, gyrotron is used for rectification, and a complex power divider network is also needed to integrate the RF power and deliver as a single rectifier . The other method, the RF energy is received from the antenna array, each cell of antenna array connects a rectifier, and the summation of dc power is delivered to load by dc network . For the first approach, the architectural is difficult to design and the loss is increased when the energy is merged in form of RF.…”

Compared with the former approach, the second one has simple configuration due to the unnecessary complex RF divider networks and it also has advantages of decreased return loss, increased rectification efficiency, easy to expansion of power capacity, and low cost.…”

A 2.45 GHz industrial, scientific and medical band rectenna with a two‐layered structure for various applications involving microwave wireless power transmission (WPT) has been designed and measured in this article. A microstrip antenna with two perfect electrical conductor walls loaded for gain enhancement is designed. In addition, a typical single‐diode compact radio frequency (RF) rectifier with a series bandpass structure is presented. The simulated RF to dc conversion efficiency of the rectifier is above 50% when the input power ranges from 0 to 28 dBm. The fabricated rectenna is compact with a dimension of 0.5λ × 0.5λ. A RF to dc conversion efficiency of about 73% is achieved under received power density of 38.5 W/m2 with a 500 Ω dc load. Due to the integration design of antenna and rectifier, the proposed rectenna is suitable to be well applied in miniaturization of rectenna array.
