“…Within a frequency range from 2.2 to 2.6 GHz at 13 dBm, we obtained energy when 100 Ω was loaded, and the increased rectenna energy storage efficiency is 80.25%, as shown in Figure 13. In terms of the measurement of DC energy [38,39] that was obtained by connecting the prototype antenna to the rectifier and voltage multiplier circuits as the block diagram show in Figure 14, this was tested on the 4, 6, 8, and 10 times voltage multiplier circuit, which had a voltage of 0.29 V, 0.31 V, 0.28 V, and 0.27 V, respectively. From the aforementioned, the 6 times voltage multiplier circuit has the highest voltage value of 0.31 V and a power value of 7.33 µW.…”

“…As a result, the researchers choose disadvantages identified by this research that is the first part of a basic dipole antenna structure [27,28] with an increasing I-shaped stub to widen the frequency [16,[29][30][31][32] and gain enhancement for the antenna by using the horn waveguide [33][34][35] and in terms of getting more energy. The second part studies the matching impedance circuit using a Radial Stub Circuit (RSC) [20,36,37] with the power frequency signal converter circuit by using a full-wave rectifier circuit with a voltage multiplier circuit [16,38,39] to increase the pressure on the rectenna system that is designed to receive power at a frequency of 510-790 MHz, which is the digital TV wireless transmission system. At present, it is widely used in Thailand [40].…”

This article presents a dipole antenna using an I-shape adding technique on both sides of the antenna's body to widen the frequency range, using a horn waveguide to gain enhancement and harvest energy by matching the circuit which is compatible with the voltage multiplier circuit at the RF frequency (510-790 MHz) in a TV digital system. Having measured the effect of the antenna, it was found that the antenna operates at a frequency range of 60.24% (450-838 MHz), a 67.79% increase from the base dipole antenna, which has again enhancement of 10.23 dB from adding the horn waveguide (60.99%). It has a pattern of energy radiating in a specific direction, and when the antenna is used with an energy harvesting circuit to get energy or power from the front direction of the TV digital antenna at a distance of 10 km, it is capable of harvesting energy of up to 7.33 µW.

This work proposes a new compact triple-band triangular patch antenna for RF energy harvesting applications in IoT devices. It is realized on Teflon glass substrate with a thickness of 0.67 mm and a relative permittivity of 2.1. Four versions of this antenna have been designed and realized with inclinations of 0°, 30°, 60° and 90° to study the impact of the tilting on their characteristics (S11 parameter, radiation pattern, gain) and to explore the possibilities of their implementation in the architectures of electronic equipment according to the available space. The antenna is also realized on waterproof paper with a thickness of 0.1 mm and a relative permittivity of 1.4 for biomedical domain. All the antennas (vertical antenna, tilted antennas and antenna realized on waterproof paper) have a size of 39 × 9 mm2 and cover the 2.45 GHz and 5.2 GHz Wi-Fi bands and the 8.2 GHz band. A good agreement is obtained between measured and simulated results. Radiation patterns show that all the antennas are omnidirectional for 2.45 GHz and pseudo-omnidirectional for 5.2 GHz and 8.2 GHz with maximum measured gains of 2.6 dBi, 4.55 dBi and 6 dBi, respectively. The maximum measured radiation efficiencies for the three antenna configurations are, respectively, of 75%, 70% and 72%. The Specific Absorption Rate (SAR) for the antenna bound on the human body is of 1.1 W/kg, 0.71 W/kg and 0.45 W/kg, respectively, for the three frequencies 2.45 GHz, 5.2 GHz and 8.2 GHz. All these antennas are then applied to realize RF energy harvesting systems. These systems are designed, realized and tested for the frequency 2.45 GHz, −20 dBm input power and 2 kΩ resistance load. The maximum measured output DC power is of 7.68 µW with a maximum RF-to-DC conversion efficiency of 77%.

“…Configurable antennas, in particular, are under the spotlight of researchers with interest in electromagnetic spectrum usage. These antennas can be implemented using a variety of technologies, and the most trending type is the microstrip antennas justified by their low profile, light weight as well as their ability to produce multiple radiation bands [1]- [3]. The rising number of wireless devices is causing spectrum congestion which may increase collisions in the broadcasting channels.…”

This paper proposes a dual band reconfigurable microstrip slotted antenna for supporting the wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications, providing coverage where both directive and omni-directive radiations are needed. The design consists of a feedline, a ground plane with two slots and two gaps between them to provide the switching capability and a 1.6 mm thick flame retardant 4 (FR4) substrate (dielectric constant Ɛ=4.3, loss tangent δ=0.019), modeling an antenna size of 30x35x1.6 mm3. The EM simulation, which was carried out using the connected speech test (CST) studio suite 2017, generated dual wide bands of 40% (2-3 GHz) with -55 dB of S11 and 24% (5.2-6.6 GHz) higher than its predecessors with lower complexity and -60 dB of S11 in addition to the radiation pattern versatility while maintaining lower power consumption. Moreover, the antenna produced omnidirectional radiation patterns with over than 40% bandwith at 2.4 GHz and directional radiation patterns with 24% bandwith at the 5.8 GHz band. Furthermore, a comprehensive review of previously proposed designs has also been made and compared with current work.
