Bioinspired transparent antenna for WLAN application in 5 GHz

Abstract

In this paper is developed a transparent antenna, bioinspired in ingae edulis mart plants, build in Indio Tin Oxide film, and flexible transparent dielectric of low cost (cellulose acetate), generated by Gielis formula, for wireless local area network application in 5 GHz (5.15–5.85 GHz). The measured bioinspired transparent antenna presented bandwidth of 4.11 GHz (4.50‐8.66 GHz), covering the WLAN band, with maximum gain of 5.44 dBi, and half power beamwidth of 126° at resonance frequency.

Bio-Inspired On-Chip Antenna Array for ISM Band60 GHz Application

“…3 and Table II shows the curves of simulated gain (dBi), at resonance frequency, of on-chip aperture-coupled antennas. According to [13], there is a relationship between the amount of metal in the radiating element and the gain in the planar antennas. At resonance frequencies, the bioinspired flower-shape antenna presents gain very close to the one observed in the circular-shape, with a difference of 1.04 dBi, however, with the insertion of one more element of same dimension, there is an increase in the power gain (3.11 dBi), which shows an expected behavior for an antenna array [5], which results in a maximum gain of 8.83 dBi.…”

“…The use of the bio-inspired forms allows the development of compact structures with larger electrical perimeters, operating at lower frequencies [12]. Plant shapes were used in the development of some antennas, built in fiberglass, denim and transparent materials, such as cellulose acetate with Indio tin oxide film, operating in UWB applications [13], LTE bands at 700 MHz [12], 2G, 3G and 4G [14], and WLAN [15][16].…”

Transparent Antenna for Green Communication Feature: A Systematic Review on Taxonomy Analysis, Open Challenges, Motivations, Future Directions and Recommendations

“…The capabilities of processing, sensing and decision-making will be equipped as well [84]. it potentially suitable for future flexible transparent electronics and wearable devices, by using ITO (indium tin oxide) offers enhanced film brittleness and moderate sheet resistance [57] [31]. The arrival of mobile communication has made antennas ubiquitous.…”

“…The receivers come in two basic structures: direct detection and ultra-high contrast. Direct detection feeds an incident RF signal to a carrier frequency detector, usually including a limited amplification stage [31] [59]. Transparent arrays will be able to solve the demand of both improved system capacity and eradicate the location limits, where antennas can be set up and viable set ups include windows of buildings and cars [49].…”

“…Other software types had also been applied to design transparent antennas, including commercial software ANSYS with MATLAB [31], Analysis Systems Designer (ANSYS) [59], and 3D electromagnetic simulation software [80]. Eight articles (9.87%) had reported on the use of other software packages to design and simulate transparent antennas.…”
