“…Because of the lower spectral density, the antenna is less prone to interference with other signals [ 147 ]. The UWB antenna made with the textile substrate can be used for on-body applications because it has minimal effect on the human body [ 148 , 149 , 150 , 151 , 152 ]. Paper-based inkjet-printed UWB antenna was introduced first in earlier studies [ 153 , 154 ].…”

The field of flexible antennas is witnessing an exponential growth due to the demand for wearable devices, Internet of Things (IoT) framework, point of care devices, personalized medicine platform, 5G technology, wireless sensor networks, and communication devices with a smaller form factor to name a few. The choice of non-rigid antennas is application specific and depends on the type of substrate, materials used, processing techniques, antenna performance, and the surrounding environment. There are numerous design innovations, new materials and material properties, intriguing fabrication methods, and niche applications. This review article focuses on the need for flexible antennas, materials, and processes used for fabricating the antennas, various material properties influencing antenna performance, and specific biomedical applications accompanied by the design considerations. After a comprehensive treatment of the above-mentioned topics, the article will focus on inherent challenges and future prospects of flexible antennas. Finally, an insight into the application of flexible antenna on future wireless solutions is discussed.

A transparent flexible co‐planar waveguide fed patch antenna using polyethylene terephthalate substrate is presented. The wideband high gain antenna having an overall dimension of 0.48λ × 0.64λ at the center frequency of 4.28 GHz is fabricated using a transparent sheet made up of Silver Tin Oxide (AgHT‐8). The performance of the proposed antenna is compared with four other nontransparent nonflexible and semitransparent flexible antennas. For the engineered design, patch geometry and feeding mechanism are kept constant whereas the substrate and patch materials are varied. Simulations are carried out using finite element method‐based full wave high‐frequency structure simulator after which the antennas are fabricated and tested. The proposed flexible transparent antenna has bandwidth in order of 40%, ranging from 3.89 to 5.9 GHz, with a notable gain over 3 dBi and efficiency greater than 80% for the entire frequency band. The bending conditions are also tested for the flexible transparent antenna which showed decent performance for sub‐6 GHz 5G and WLAN applications.

“…Nevertheless, the cost, the weight, and the sensitivity to corrosion can limit their usage for composite laminate integration. Recent studies have presented various conductive materials with flexible and durable mechanical properties as a replacement for metals [4][5][6][7]. The microwave performance of an antenna made of full carbonfibre fabric embedded into a full composite laminate panel is presented in [4].…”

This study highlights the integration potential of a highly conductive fabric into composite materials based on an efficient fabrication technology for coplanar waveguide flexible composite ultra‐wideband antenna radiating from 3.3 to 12 GHz. A thin sheet of a highly conductive fabric has been embedded by infusion process in a thin composite laminate made of E‐glass fibre mat and epoxy resin to fabricate a flexible conductive composite laminate. The antenna elements have been machined precisely by laser etching. The measured radiation efficiency reaches over 70% throughout the antenna operating frequency band with satisfactory radiation patterns and gain. The composite antenna exhibits reliable performance under different bending conditions as presented by the measurements. The high radiation performance, the seamless integration process and flexible mechanical properties of such composite antennas pave the way for their promising potential for integrating efficient antennas into various devices and objects made of composite laminate materials.
