“…Nevertheless, the structure is very complex and requires low-loss interconnects as well as occupying a large volume (290×130 2 π mm 3 ). At mmWave bands, implementing such large area arrays is straightforward on planar flexible substrates [50], [74]. Therefore, beamforming networks can enable long-range wide-beamwidth energy harvesters beyond 24 GHz.…”

“…Various implementations have been presented using this fabrication method and all implementations were based on common geometry microstrip patch antennas [24], [50]. Such rectennas can achieve a DC output close to or surpassing their counterparts on rigid PCBs as in [74]. However, they cannot be classified as fully low-cost components as they still rely on expensive high-frequency substrates which can be over 90× more expensive than fiberglass or plastics [89].…”

“…For instance, the LCP patch rectenna array in [50] based on the Rotman beamforming lens achieves a longer operation range than other harvesters operating at the same frequency. Furthermore, the use of a similar beamforming patch array was demonstrated in [74] for long-range retro-directive backscatter communications for RFID applications at 28 GHz. Given the 75 dBm EIRP of 5G systems, the beamforming tag would have a read-range of 1.8 km.…”

“…Such range is not matched by UHF RFID systems and demonstrates the benefits of mmWave power harvesting and passive wireless communications. The practical demonstration with a 48 dBm EIRP in [74] shows a very long tag readrange of 64 m, which exceeds conventional UHF RFID which is often around 20 m. Although the RFID Rotman-lens array backscatter modulator was powered using a flexible solar cell [74], given its low power consumption of 2.64 µW it can be powered using a rectenna based on the same Rotman lens, similar to the implementation in [50]. Therefore, integration of rectennas with backscattering modulators based on shared antenna arrays will be a promising area for mmWave power harvesting where beamforming networks outperform singledirection mmWave-ID Van Atta arrays such as [110], [111], Combining the reviewed advances in mmWave antennas, rectifiers, and intermediate reflectors, a mmWave-powered network shown in Fig.…”

The broad spectrum available at millimeter-wave (mmWave) bands has attracted significant interest for a breadth of applications, with 5G communications being the main commercial drive for mmWave networks. Wireless power transmission and harvesting at mmWave bands have attracted significant attention due to the potential for minimizing the harvesting antenna size, allowing for more compact rectennas. For a fixed antenna size, the received power increases with frequency. Nevertheless, several challenges lie in realizing high efficiency antennas and rectifiers at mmWave bands. This paper reviews the recent advances in mmWave rectenna design at a component-and system-level. Low-cost antennas and components for mmWave power harvesting, such as high efficiency scalable rectifiers on polymers and high radiation efficiency antennas on textiles, are reviewed. Both the antenna and rectifier can be realized using low-cost fabrication methods such as additively-manufactured circuits and packages, in addition to digital integrated circuits (ICs) for the rectifiers. Finally, this paper provides an overview of future antenna design challenges and research directions for mmWave power harvesting.

In the recent wireless application, an electrically controllable beam is an essential standard to increase gain and decrease interference. While, achieving a steerable beam in the desired angles using a low-cost microwave structure with reliable performance is challenging. This article provides a study for modelling and design steps a beamforming network based on Rotman lens in the microstrip model. The explanation of the Rotman lens structure is introduced. Then the steps to derive the beam and receive contour of the lens are illustrated. Further, the derived equations formulated on the geometric optics are provided besides all the design variables explanations. A parametric study of the lens design variables is demonstrated. At the same time, the lens performance is examined in terms of the path length error of the beam ports to the radiated elements. A prototype lens including 5 × 4 ports is implemented. Keywords Microstrip Rotman lens • Beamforming • Steerable antenna 1 IntroductionMost modern radar and communication systems require the scanning of wide areas by several beams, preferably simultaneously, such as radio frequency identification (RFID) [1], fifth-generation platforms (5G) [2, 3], MIMO system [4], and ultrawideband (UWB) antenna [5]. Moreover, the development of a suitable radiation system and feeding networks can play an essential part in the development of communication systems of the new generation. In some instances, simultaneous beam scanning with array antennas can be accomplished. However, Typical technologies use phase shifters for antenna arrays [6-8], or array feeds for reflector systems with a switching matrix [9]. Furthermore, the phase-shift approach can be costly for these

Wireless imaging, equipped with ultralow power wireless communications and energy harvesting (EH) capabilities, have emerged as battery-free and sustainable solutions. However, the challenge of implementing wireless colour imaging in wearable applications remains, primarily due to high power demands and the need to balance energy harvesting efficiency with device compactness. To address these issues, we propose a flexible and wearable battery-free backscatter wireless communication system specially designed for colour imaging. The system features a hybrid RF-solar EH array that efficiently harvests energy from both ambient RF and visible light energy, ensuring continuous operation in diverse environments. Moreover, flexible materials allow the working system to conform to the human body, ensuring comfort, user-friendliness, and safety. Furthermore, a compact design utilizing a shared-aperture antenna array for simultaneous wireless information and power transfer (SWIPT), coupled with an optically transparent stacked structure. This design not only optimizes space but also maintains the performance of both communication and EH processes. The proposed flexible and wearable systems for colour imaging would have potentially applications in environmental monitoring, object detection, and law enforcement recording. This approach demonstrates a sustainable and practical solution for the next generation of wearable, power-demanding devices.
