“…Indeed, rectennas are not only used in the microwave spectrum; in fact, they were designed to transform solar energy into DC, having a similar role to solar cells [ 15 ] (the history of rectennas can be found in [ 16 ]). The most common approach for rectennas in the microwave and millimeter-wave range is to integrate antennas with Schottky diodes; in this way, an integrated circuit fully compatible with the CMOS process can be achieved [ 17 ] up to 100 GHz [ 18 ], even reaching a few terahertz [ 19 ]. Figure 2 represents the schematic of a THz Schottky diode on a gallium arsenide (GaAs) substrate, using thin n + -doped and low n -doped epitaxial layers [ 19 ].…”

This manuscript presents an overview of the implications of nanomaterials in harvesting ambient electromagnetic waves. We show that the most advanced electromagnetic harvesting devices are based on oxides with a thickness of few nanometers, carbon nanotubes, graphene, and molybdenum disulfide thanks to their unique physical properties. These tiny objects can produce in the years to come a revolution in the harvesting of energy originating from the Sun, heat, or the Earth itself.

“…There are many other techniques like silicon lens [68], ion irradiation [69], asymmetrical patch [70], impure Si wafer (high resistivity Si) [71,72], and split ring resonators (SRRs) [73] are some of the popular and trending techniques recently, which have been reported for enhancing the radiation characteristics of OCAs. In [68], a rectangular-shaped Si lens is used to increase gain by 8-13 dB.…”

With the evolution of 5G and 6G network architectures, the demand for highly compact system-on-chip-based devices with high data transfer capabilities has been increased significantly. While the advancement of very large-scale integration technology with the continuous scaling of complementary metal–oxide–semiconductor nodes put forward to integrate different functional modules of a complete system on a single IC board, the antenna being the largest component still remains outside of the chip. Integration of the antenna and other functional modules of a system on the same chip leads to produce a really compact and economical design. Though on-chip antenna (OCAs) have several other advantages and emerging applications, they have some design challenges in terms of low gain due to losses in the substrate, requirement of miniaturization at lower microwave frequencies (LMFs) (particularly, below 10 GHz), unavailability of proper design rules, etc. In this paper, analyzing the design challenges of OCAs, their current research trends and future perspective applications are discussed.

“…The capacitor used in this circuit is a type of Tantalum SMD with a working frequency greater than 2.4 GHz, making it easier to optimize both physically and in terms of calculations. At the same time, optimization [14] on the input impedance of the CMOS circuit chip with a voltage multiplier, where the measurement is challenging and has a reasonably complex stage. To optimize the voltage output in the circuit design, the capacitor on the circuit will cross the load.…”

The design and implementation's novelty simultaneously utilizes the antenna's frequency, polarization, and feed structure to maximize the harvested RF energy and become a microstrip communication circuit for wireless sensor or communication systems in IoT devices. In addition, the optimization of the parallel circuit configuration has a voltage doubler model with an integrated parallel system and thin-film solar cells. Implementation of the antenna structure has two-line feeds in one antenna. Usage both feeds have the same function as CPW circular polarization. Another advantage is that there is no miss-configuration when installing the port exchanges when using both output ports simultaneously. The 2-port antenna has an area of 1/2 per port (where accessible wavelengths work well at the 2.4 GHz frequency). It has been shown to achieve a relatively narrow bandwidth of 86.5 percent covering WiFi frequency band networks and IoT communications. It does not require additional filters and analog matching circuits that cause power loss in the transmission process in parallel voltage doubler circuits. Integrating a reflector on the CPW antenna with two ports for placement of thin-film solar cells provides antenna gain of up to 8.2 dB. It provides a wide beam range with directional radiation. Using a multi-stage parallel to increase voltage output and integrated with a thin-film solar cell converter proves efficient in the 2.4 GHz frequency band. When the transmission power density is -16.15 dBm with a tolerance of 0.023, the novel energy harvester configuration circuit can produce an output voltage of 54 mV dc without adding solar cell energy. And Integrated thin-film solar cell a light beam of 300 lux in the radiation beam area of -16.15 dBm, the energy obtained has a value of 1,74467V. It also shows that the implementation of this configuration can produce an optimal dc output voltage in the actual indoor and outdoor ambient settings. The optimization of antenna implementation and the communication process with Multiple signal classifications improves the configuration of antennas that are close to each other and have identical phase outputs. It is instrumental and efficient when applied to IoT devices.
