“…Depending on the type of application, it is vital to choose a suitable flexible material as a substrate. In last few decades, various types of flexible materials have been adopted as substrates for antennas to provide flexibility including textile or fabrics [ 44 , 155 , 156 , 157 , 158 , 159 ], paper [ 160 , 161 , 162 , 163 , 164 , 165 ] and polymers [ 3 , 7 , 8 , 10 , 14 , 15 , 26 , 28 , 29 , 39 , 55 , 57 , 58 , 59 , 61 , 62 , 63 , 73 , 77 , 78 , 79 , 80 , 81 , 85 , 86 , 104 , 139 , 148 , 149 , 166 , 167 , 168 , 169 , 170 , 171 , 172 , 173 , 174 , 175 , 176 , 177 ...…”

“…Teflon is a commercially available PTFE polymer having a combination of good mechanical, electrical, thermal and anti-friction properties. With a very high melting point where its functionalities continue over 260 °C [ 204 ], Teflon is a well-known flexible material because of this thermal stability and resistance to change in temperature and as well as its resistance to corrosion and stable dielectric constant over a wide range of frequencies [ 176 ]. Its properties serve to provide flexibility in antenna designs with PTFE Teflon aptly utilised in the RFID tag antenna designs.…”

Flexible substrates have become essential in order to provide increased flexibility in wearable sensors, including polymers, plastic, paper, textiles and fabrics. This study is to comprehensively summarize the bending capabilities of flexible polymer substrate for general Internet of Things (IoTs) applications. The basic premise is to investigate the flexibility and bending ability of polymer materials as well as their tendency to withstand deformation. We start by providing a chronological order of flexible materials which have been used during the last few decades. In the future, the IoT is expected to support a diverse set of technologies to enable new applications through wireless connectivity. For wearable IoTs, flexibility and bending capabilities of materials are required. This paper provides an overview of some abundantly used polymer substrates and compares their physical, electrical and mechanical properties. It also studies the bending effects on the radiation performance of antenna designs that use polymer substrates. Moreover, we explore a selection of flexible materials for flexible antennas in IoT applications, namely Polyimides (PI), Polyethylene Terephthalate (PET), Polydimethylsiloxane (PDMS), Polytetrafluoroethylene (PTFE), Rogers RT/Duroid and Liquid Crystal Polymer (LCP). The study includes a complete analysis of bending and folding effects on the radiation characteristics such as S-parameters, resonant frequency deviation and the impedance mismatch with feedline of the flexible polymer substrate microstrip antennas. These flexible polymer substrates are useful for future wearable devices and general IoT applications.

“…In the last decade, ultra wide band (UWB) antennas have received much attention in many different fields. For instance, flexible antennas have been successfully applied to communications service (PCS 1.8/1.9 GHz), wireless local area network (WLAN 2.45 GHz) and wireless networks (around 5.4 GHz) [1][2][3]. Strategies have been elaborated to develop or adopt a different kind of materials in order to realise flexible printed antennas [4][5][6][7][8].…”

New generations of printed flexible antennas are playing an important role in wireless communication systems. The ultra wide band and wearable possibilities are critical aspects of these kinds of antennas. In this study, the proposed antenna is an elliptical monopole fed by a coplanar waveguide; it uses a kapton substrate and it is optimised to work from 1 to 8 GHz. In the case of copper, a conductive nanocomposite material based on a polymer (polyaniline: PANI) and charged by multiwalled carbon nanotubes (MWCNTs) is exploited. The flexibility of both the kapton substrate and the nanocomposite (PANI/MWCNTs) provides the ability to crumple the antenna paving the way to potential applications for body‐worn wireless communications systems. In this study, the performance of the antenna is investigated in terms of return loss, radiation patterns and gain for both crumpled and uncrumpled antennas. The results confirm that performance remains at a good level when the antenna is crumpled.

“…Antennas that can operate in such bands with physical flexibility can be integrated with other flexible devices to transmit and receive signals in numerous applications [3,4]. Various designs of flexible antennas based on flexible substrates have been proposed in the literature [5,6]. However, few studies have shown the possibility of the antenna which can operate both in WLAN and UWB [7].…”

A compact broadband flexible antenna is proposed for applications in wireless local area network (WLAN) and upper ultra-wideband (UWB) systems, which can operate in the bandwidths of 2.4-2.484 GHz and 3.5-10.6 GHz with a reflection coefficient of <−10 dB. The presented antenna coated with bio-compatible ultra-thin parylene-c is fabricated on a thin polyimide substrate with a thickness of 127 μm. The characteristics of the proposed antenna are measured under bending and flat conditions. The measured results showed that the antenna is suitable for integration with flexible electronic devices.
