“…For this reason, four is the optimal number of antennas that can be mounted on top of the solar panel. The normal range of the received UHF power density is from 30 to 100 mW/m 2 [13]. This depends on the following factors: the alignment between the transmitting and receiving antennas, the distance separation between them, and the size of the receiving antenna.…”

This paper presents a Sunlight-Radio Frequency (RF) energy harvesting system built on Solar Panel Mesh Dipole Antenna integration. The dipole antenna mesh is mounted on the surface of the solar panel at the separations between the cells. This configuration maximizes the absorption of both solar and RF energies. Further, the multiple mesh antennas are integrated vertically to increase the RF harvested power. Each antenna output is connected to a six-stage RF-Voltage Doubler Rectifier (RF-VDR) circuit to convert the RF signal to a direct current (DC) and added to the solar panel DC output. This paper involves the design analysis of the antenna parameters, the integration process, and the design of the RF matching circuit. Prototype tests show that the proposed mesh dipole antenna has 83% efficiency. This is better than earlier similar designs published. From previous designs, the measured RF to DC conversion efficiency (CE) of the VDR circuit was merely 62% when the RF input equals -14 dBm. Moreover, the solar panel efficiency has been enhanced by 41.3 % when the input RF power density equals 49.16 mW/m 2 . Finally, the results proved that the proposed solar antenna system achieves 28.5 % power CE and outperforms the others that use transparent patch antennas.

“…Moreover, making the IoT relay antennas invisible by means of transparent electronics thus represents another promising prospect for the telecommunication markets. − The frequencies proposed for the upcoming 5G network would result in shorter broadcast distances and network dead zones. Additional access points and signal repeaters embedded into the existing infrastructure help mitigate these issues through embedding transparent antennas into the windows by means of metallic meshes , /nanowires or transparent conductive oxides (TCOs). ,, The present article demonstrates the first TCO-based transparent antenna processed entirely by ALD. Optically transparent antennas based on both AZO and GZO have been previously demonstrated (comprehensive reviews on TCO-based antennas here ,, ).…”

Study of Gallium-Doped Zinc Oxide Thin Films Processed by Atomic Layer Deposition and RF Magnetron Sputtering for Transparent Antenna Applications

Gallium-doped zinc oxide (GZO) films were fabricated using RF magnetron sputtering and atomic layer deposition (ALD). The latter ones demonstrate higher electrical conductivities (up to 2700 S cm–1) and enhanced charge mobilities (18 cm2 V–1 s–1). The morphological analysis reveals differences mostly due to the very different nature of the deposition processes. The film deposited via ALD shows an increased transmittance in the visible range and a very small one in the infrared range that leads to a figure of merit of 0.009 Ω–1 (10 times higher than for the films deposited via sputtering). A benchmarking is made with an RF sputtered indium-doped tin oxide (ITO) film used conventionally in the industry. Another comparison between ZnO, Al:ZnO (AZO), and Ga:ZnO (GZO) films fabricated by ALD is presented, and the evolution of physical properties with doping is evidenced. Finally, we processed GZO thin films on a glass substrate into patterned transparent patch antennas to demonstrate an application case of short-range communication by means of the Bluetooth Low Energy (BLE) protocol. The GZO transparent antennas’ performances are compared to a reference ITO antenna on a glass substrate and a conventional copper antenna on FR4 PCB. The results highlight the possibility to use the transparent GZO antenna for reliable short-range communication and the achievability of an antenna entirely processed by ALD.
