“…The conversion of the impedance into resistance occurs if the signal is received by the antenna at the resonant frequency. Figure 8b [69,70] shows a simple equivalent antenna circuit functioning at a resonant frequency. Figure 9 indicates that the microstrip antenna consists of a radiation patch, a ground plane, a dielectric substrate, and a nourishing point that could be used in a variety of ways.…”

The investigation into new sources of energy with the highest efficiency which are derived from existing energy sources is a significant research area and is attracting a great deal of interest. Radio frequency (RF) energy harvesting is a promising alternative for obtaining energy for wireless devices directly from RF energy sources in the environment. An overview of the energy harvesting concept will be discussed in detail in this paper. Energy harvesting is a very promising method for the development of self-powered electronics. Many applications, such as the Internet of Things (IoT), smart environments, the military or agricultural monitoring depend on the use of sensor networks which require a large variety of small and scattered devices. The low-power operation of such distributed devices requires wireless energy to be obtained from their surroundings in order to achieve safe, self-sufficient and maintenance-free systems. The energy harvesting circuit is known to be an interface between piezoelectric and electro-strictive loads. A modern view of circuitry for energy harvesting is based on power conditioning principles that also involve AC-to-DC conversion and voltage regulation. Throughout the field of energy conversion, energy harvesting circuits often impose electric boundaries for devices, which are important for maximizing the energy that is harvested. The power conversion efficiency (PCE) is described as the ratio between the rectifier’s output DC power and the antenna-based RF-input power (before its passage through the corresponding network).

“…It has been determined that the simulated resonance bandwidth of the developed antenna is 7.05 to 8.72 GHz (1.67 GHz bandwidth), while the measured resonance bandwidth is 6.5 to 8.85 GHz (2.35 GHz bandwidth). [34] Wet chemistry and 3D printing techniques have been used in numerous research in the aviation industry, especially those carried out in the last five years. [34][35][36][37][38][39][40][41] A harmonic load-bearing antenna design was developed on the composite structure utilizing innovative processing techniques.…”

A simple method for creating lightweight and inexpensive microstrip patch antennas using reduced graphene oxide or acetylene black added epoxy resin was developed. The biggest goal in the method is optimizing the appropriate chemicals and production processes for producing the materials with the designed properties. Five examples of an inset‐fed microstrip patch antenna operating at approximately 2.0–12.0 GHz were designed based on the antenna‘s basic analytical formula. Their models were created in a 3D electromagnetic simulation environment. After examining the performance results of the design, the appropriate design models were produced with both 3D printer technology and wet‐chemical methods, and the experimental results were compared with the simulation results. The produced reduced graphene oxide or acetylene black added samples′ structure was illuminated with scanning electron microscope images, FTIR and Raman spectroscopy analysis. The measured S11 characteristics of the antennas provide better performance as compared to the simulated results. The measured S11 parameters for the two and three frequency bands fell substantially below −10 dB. As a result of the dielectric constants of the materials and the fabrication of the radiation plane, horizontal shifts were detected in the measurement outcomes.

“…First, for the antenna substrate materials, a dielectric constant ( r ) and thickness (h) are studied. Several different materials have been studied as the antenna substrates: paper, textile, polyethylene terephthalate (PET), kapton polyimide, polydimethylsiloxane (PDMS), and nickel aluminate [3,4,5,6,7,8]. In particular, polytetrafluorethlene (PTFE) and FR4 have been commonly chosen for RF and microwave antennas, and their r are 2.0 -2.3 and 3.9 -4.7, respectively.…”

We perform systematic numerical simulations for carbon nanotube (CNT) film microstrip antennas to fabricate flexible and durable applications in terms of various device design parameters. The selection of appropriate materials for conductive films and a substrate of the conformable and robust microstrip antennas are crucial to increase the radiation efficiency and to reduce the losses while maintaining the mechanical properties. CNTs have been spotlighted as a promising nanomaterial, exhibiting excellent electrical and mechanical performances as desirable features for microwave wearable devices. Considering the material properties of the conductor and the substrate, we examine the possible ranges of the CNT film conductivities, conductive film thickness, and a dielectric constant and thickness of a substrate. Furthermore, we model non-uniform spatial distributions of conductivity in the CNT film to assess their impact on the antenna performance. Our extensive studies of material constants and conductivity spatial patterns propose design guidelines for optimal microstrip antennas made of CNT conductive films operating in microwave frequencies.
