“…Because, as noted, our HDA design is readily scaled to many other frequency bands, the associated HDAAs will share the properties described and validated herein. Thus, HDAbased rectenna arrays have the potential to impact many WPT receiver applications associated, for example, with wireless powered IoT systems [41] and with solar power satellite (SPS) and other point-to-point microwave and millimeter-wave power beaming systems [42], [43].…”

The theoretical analysis of beam-steerable, broadside-radiating Huygens dipole antenna arrays (HDAAs) is presented. Linear HDAAs with different numbers of elements are investigated and compared with full-wave simulations. Their attractive performance characteristics for wirelessly powered IoT applications are emphasized. Each Huygens dipole antenna (HDA) is an electrically small, linearly polarized, efficient, unidirectional radiating element. Linear HDAAs are confirmed to achieve high directivity beams in one principle plane and significantly broad beamwidths in the orthogonal principle plane. Very stable gain variation when their main beam is steered is demonstrated. A practical beam-steerable, broadside-radiating, linear HDAA is developed that employs an experimentallyverified HDA and is facilitated by a microstrip power-divider feed network. The entire HDAA design is ultrathin (λ0/240.87), lying only on a single piece Rogers Duroid TM 5880 copper-clad substrate. A proof-of-concept 3-element HDAA prototype excited with a 3×3 Butler matrix centered at 2.45 GHz was designed, fabricated and measured. The measured results, in very good agreement with their simulated values, demonstrate the efficacy of the linear HDAA designs and their potential usefulness for wireless power transfer (WPT) systems dedicated to emerging IoT applications that require power be directed towards terminals in multiple specified directions with broad area coverage at each one.

“…WPT and energy via radio waves could, therefore, be effectively integrated into the backscatter communication devices to enable simultaneous wireless information and power transfer (SWIPT) and batteryless sensors, actuators, and smart devices for a range of IoT applications [41]. Prior to backscatter communication, RF WPT was mainly developed for high-power microwave and millimeter-wave beaming for space applications [42], [43], which is generally not applicable to the urban and domestic environments since it exceeds the safety limit of RF power radiation (e.g., effective isotropic radiated power (EIRP) > 20 dBm). Consequently, to wirelessly power backscatter tags, the energy could be either from the dedicated backscatter RF transmitter or from the ambient wireless signals (ambient backscattering) with relatively low power density [44].…”

“…Moreover, the proposed hybrid electromagnetic solar rectifier circuit is flexible. It was shifted to be optimal according to user's needs [31,32]. As the hybrid electromagnetic solar rectifier circuit works on the same frequency band or the same frequency band on each low band port, each port shares the power with the same value.…”

The main challenge faced by RF energy harvesting systems is to supply relatively small electrical power to wireless sensor devices using microwaves. The solution is to implement a new device in a circularly polarized rectenna with circular polarization sensitivity integrated with a thin-film solar cell. Its dual-feed antennas are connected to a 2 × 4 asymmetric hybrid coupler and a multi-stage voltage doubler rectifier circuit. This configuration has a 2 × 4 asymmetric hybrid coupler used to produce 4 outputs with a 90-degree waveform phase difference. The two ports can independently be connected to the wireless sensor circuit: radiofrequency harvesting of hybrid energy solar and information equipment can be carried out with these two antennas. The Dual-Feed circular patch antenna has a two-port bandwidth of 137 MHz below −15 dB and an axial ratio of less than 3 dB, with a center frequency of 2.4 GHz with directional radiation and a high gain of 8.23 dB. It can be sensitive to arbitrary polarization of the input voltage multiplier waveform to overcome uncertainty in empirical communication environments. A parallel structure is arranged with a thin film solar cell integration from the transmitter with an output voltage of 1.3297 V with a compact composition and RF energy. The importance of adopting a wireless sensor strategy with circular polarization sensitivity and integrated RF solar energy harvesting rather than a single source method makes this research a significant novelty by optimizing the analysis of multiple wireless sensor signal access.
