“…However, the solar cells would still serve only as energy‐harvesting parasitic components under the antennas, and their utilization would decrease due to the antenna shadow. The use of solar cells as radiators has recently gained considerable attention as a means to solve this problem 14–20 . To ensure compatibility between the solar cell DC loop and the antenna radio frequency (RF) loop, filters have been introduced 14–17 ; however, the use of additional filters limits the portability and miniaturization of the system, as well as increases its cost.…”

This paper proposes a differentially fed suspended plate antenna (SPA) integrated with solar cells. A structure of hollow cylinders is used to support the patch and enhance the gain by suppressing any unwanted high-order mode. More importantly, the cathode of the solar cells is connected to the antenna ground to improve the compatibility of the antenna and solar cells without introducing additional filters. Differentially fed L-shaped coaxial probes feed the SPA to enhance the bandwidth. The anode and the cathode of the two solar cells are connected and located directly above the patch. A prototype of the solar cell SPA is fabricated and measured to verify the stability of its radiation and energy-harvesting performance. The measurement results show that the bandwidth of the proposed solar cell SPA is 3.2-5.1 GHz for wideband application, and its gain is higher than 9.51 dBi in the operating band.

“…The ground plane separating the primary patch connection and the double U slot is smaller than the resonance size so that radiation has propagated to the main patch element. Assuming the circular patch resonates in its dominant mode, the accumulation of the slot optimization model concerning the frequency formed on the patch surface is expressed in Equation (2).…”

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.

The antennas that share radiators with solar cells are applicable to collect energy and integrate radio frequency functions. In this paper, a solar cell integrated multiband antenna is proposed on the basis of Vivaldi antenna structure. Unlike prior research, it has the capacity to reconfigure working frequencies and radiation performance of the antenna through optical control of the solar cell. The purpose of reconfiguration is achieved by means of two switching diodes placed between the differential Vivaldi radiator and conducted via biasing from the solar cell. The integrated solar cell functions both as part of the radiator and as the biasing source for switching diodes. According to the simulation and measurement results, the antenna performs consistently at around 5 GHz, while the radiation performance can be reconfigured at 1.16 and 3 GHz under illumination. In this way, the proposed antenna can fulfill various functions such as green energy collection, wireless communication, and light detection, which makes it applicable in the Internet of Things for low‐power wireless sensor terminal.
