Ring slot CP antenna for the hybrid electromagnetic solar energy harvesting and IoT application

Abstract

The research proposed a compact antenna integrated with dual-function solar cells to optimize internet of things (IoT) communication devices and energy harvesting. The use of integrated solar cells with electromagnetic elements as antennas and energy-gathering in a design is a solution for wireless communication sensors and simultaneously electromagnetic and solar energy harvesting. Radiation performance testing of solar cell antennas and optical experiments were carried out to test the ability of solar energy collection. A double feed ring slot circular polarization (CP) antenna coplanar antenna with a configuration has highly sensitive to vertical and horizontal waves. It is to accommodate the impact of circular polarization wave and solar cell distortion on antenna performance. This technology promises green communications, renewable energy, and environmental protection to combine wireless communication and green battery components. The study presents the performance and design results of a double line-feed microstrip antenna circuit connected with CP antenna on the S-band for IoT communication by accommodating electromagnetic energy transmission. The importance of adopting an integrated radio frequency (RF) solar energy harvesting strategy rather than a single source method makes this research very significant in its novelty by optimizing the analysis of multiple signal access in IoT communications.

A review of the state of art and prospects in energy storage systems for energy harvesting applications

“…Li-ion batteries work between the electrodes during the chemical reaction of charging and discharging [91]. The overall reaction is represented in (6).…”

“…Energy harvesting is a technique that captures, harvests, or scavenges various unused or ambient sources of energy e.g., sun, heat, vibration, and wind, into electrical energy [1]- [44]. Sources for energy harvesting are divided into large scales such as solar PV [6], [13], [15], [33], [39], [45], [46], wind [46]- [50], tidal [30], [51], and geothermal [35], [40], [52], [53], and then on a small scale such as electromagnetic [6], [9], [32], mechanical [19], [37], [54], [55], and heat [2], [15], [24], [56], [57]. However, in recent years, largescale energy harvesting has been more widely viewed and developed.…”

“…Energy harvesting on a large scale, such as using solar PV [6], [13], [15], [33], [39], [45], [46] and wind turbines [46]- [50], is subjected to fundamental limitations, such as its inherently intermittent nature. Because of this, the amount of energy that can be captured from solar photovoltaic or wind energy to satisfy the continuous load demand is much constrained.…”

C-Slot Circular Polarized Antenna for Hybrid Energy Harvesting and Wireless Sensing

“…The capacitor values are selected with values of 100µf and 10pf, so the charge time constant is much more extended than the input sine wave period (Bhattacharjee et al, 2018). Therefore, based on the analysis of the circuit construction method, determining the value of each component is based on the analysis in Figure 3, and then optimization is performed in the research to obtain the values of components that yield the highest power output (Mujahidin & Kitagawa, 2023).…”

A new printed multiband fractal triangular antenna for wireless application

“…Fractals refer to segments that are broken or uneven and feature self-similarity or self-affinity within their geometrical structure [7]. For multiband operation, many fractal antenna approaches (Minkowski [8], [9], Sierpinski [10], Hilbert curves [11], fractal tree antennas [12], [13], Cantor [14], shaped fractals [15]- [18], slotted antenna [19], [20], and koch curves [21]) have been proposed in the literature. A small, miniature star fractal antenna for wireless applications with a gain that can approach 4.85 dB was described by Nejdi et al [22].…”
