“…Solving (2) to find r, the minimum antenna dimension for a lossless antenna (µ = 1) with a 20 MHz to 40 MHz bandwidth in free space is 5.72 m. Other considerations for the design of antennas to be deployed in polar environments are that they should be compact, lightweight and robust to facilitate transport and continuous operation. The use of wiremesh as a reflector has been common since the development of some of the earliest radar systems [16], [17], however more recently there has been interest in using wire-mesh structures as the radiating element to design lightweight [18] or optically transparent antennas [19]. The flexibility and reduced weight of wire-mesh makes it suitable for the construction of an HF/VHF antenna for ice-penetrating radar.…”

A novel high frequency (HF) to very high frequency (VHF) wire-mesh dipole antenna design for use in polar regions is discussed and evaluated. The antenna was designed to be lightweight, readily demountable, and acceptably robust. This is an initial step in the development of a ground-based, phasesensitive, synthetic aperture imaging system for use on an autonomous rover platform. The results of initial trials on the Rhône Glacier, Switzerland in August 2019 are discussed, with particular attention being paid to the effect on antenna performance of high surface water content. Including the effects of surface water resulted in good agreement between field results and modelled performance.

This paper presents optically transparent dipole antennas with innovative meshes for printing processes. The influence on antenna performance of the meshing geometry, the width and the pitch of dipole are investigated. The study shows that, for a given width, an increase of the performance with a twin small pitch with circle geometry. Furthermore, the antennas with an optical transparency of 70% present a loss of the realized gain around 0.35% compared to an opaque conventional dipole antenna with the same width.

“…Optically visible antennas provide better potential for RF energy harvesting, since they are transparent and can be easily integrated into the environment without affecting the esthetics of car windscreen, building panes, households, and wearable electronic devices. The transparent conductive films used for the design of transparent antennas are doped metal oxide films, 3 an ultra-metal thin films such as copper, silver, and gold, 4 wired metal mesh 5 and micro metal mesh films. 6 In this paper, metal oxide films are used, as they provide better transparency compared to the other materials.…”

This paper presents a novel ultra‐wideband rectenna which consists of a transparent Vivaldi antenna and a wideband rectifying circuit for radio frequency energy harvesting. The antenna is realized on a 2.2‐mm‐thick soda‐lime glass substrate coated with fluorine‐doped tin oxide of thickness 650 nm. It provides an optical transmittance greater than 80% in the visible region. The rectifying circuit with a cascaded matching network and the Greinacher doubler circuit are fabricated on an FR4 substrate with a thickness of 0.8 mm. The antenna provides the best matching characteristics and the realized peak gain is 3.2 dBi. The designed matching network enables maximum power transfer from the antenna to the rectifier. The rectenna provides a peak power conversion efficiency of 69% for −10 dBm input power. The proposed antenna can be realized on the windscreen of automobiles and glass windows without causing any obstruction to normal view.
