Introduction

The rapid development of electronic devices has led to an increasing demand for efficient and renewable energy sources. Various devices such as wireless sensors, cameras, and LED lights can operate with relatively low currents, making it essential to design new and innovative energy harvesting solutions. One promising approach is the use of rectenna technology, which utilizes electromagnetic waves to convert energy into electrical energy. This study focuses on the design and analysis of a dualband microstrip antenna array for energy harvesting at frequencies of 900 MHz and 2100 MHz.

Background and Motivation

The increasing demand for energy-efficient devices has led to a growing interest in renewable energy sources. Traditional energy sources such as fossil fuels are becoming increasingly scarce and contribute to environmental degradation. In contrast, electromagnetic waves are abundant and can be harnessed using rectenna technology. A rectenna is a device that converts electromagnetic wave energy into electrical energy, making it an attractive solution for energy harvesting.

Rectenna Technology

A rectenna is a device that consists of a receiving antenna and a power collecting antenna. The receiving antenna captures electromagnetic waves, while the power collecting antenna converts the energy into electrical energy. The design of a rectenna is critical to its performance, as it must be able to efficiently convert electromagnetic waves into electrical energy. In this study, we focus on the design and analysis of a dualband microstrip antenna array for energy harvesting.

Dualband Microstrip Antenna Array

A dualband microstrip antenna array is a type of antenna that can operate at two different frequencies. In this study, we designed a dualband microstrip antenna array for frequencies of 900 MHz and 2100 MHz. The antenna array consists of a series of microstrip patches that are arranged in a specific pattern to achieve the desired frequency response. The design of the antenna array is critical to its performance, as it must be able to efficiently capture electromagnetic waves at both frequencies.

Energy Harvesting Process

The energy harvesting process involves channeling electromagnetic waves received by the antenna into a voltage multiplier series. This circuit serves to increase the voltage of the signal received so that it can be used to charge electronic devices that require low currents. With the right design, this process can be done with high efficiency, allowing the use of energy sources that were previously unused.

Benefits and Potential

The development of this dualband microstrip microstrip antenna prototype is very relevant to the current needs, where small and portable devices are increasingly popular. With the harvesting capability of electromagnetic waves, devices such as wireless sensors can operate longer without the need to change the battery frequently. This of course will reduce battery waste and contribute to environmental sustainability.

Methodology

The methodology used in this study is the microstrip line method, which is expected to produce antennas according to the desired specifications. The design of the dualband microstrip antenna array was performed using computer-aided design (CAD) software, and the performance of the antenna was analyzed using simulation tools.

Results and Discussion

The results of this study show that the dualband microstrip antenna array is able to efficiently capture electromagnetic waves at both frequencies of 900 MHz and 2100 MHz. The energy harvesting process was also found to be efficient, with a high voltage output achieved using the voltage multiplier series. The results of this study demonstrate the potential of rectenna technology for energy harvesting and highlight the importance of designing efficient and effective antennas for this application.

Conclusion

In conclusion, this study has demonstrated the potential of rectenna technology for energy harvesting using a dualband microstrip antenna array. The results of this study show that the antenna is able to efficiently capture electromagnetic waves at both frequencies of 900 MHz and 2100 MHz, and the energy harvesting process was found to be efficient. The development of this technology has the potential to contribute to environmental sustainability by reducing battery waste and providing a new source of renewable energy.

Future Work

Future work in this area could involve further development of rectenna technology, including the design of more efficient antennas and the development of new materials and techniques for energy harvesting. Additionally, the integration of rectenna technology with other energy harvesting technologies, such as solar panels and wind turbines, could provide a more comprehensive solution for energy harvesting.
