“…In this case, the main challenge lies in the formulation and characterization of tissue-emulating materials. Example phantoms and tissue recipes reported in the literature are given in [5]. In real-life scenario, the antenna is intended to be implanted into the human body, subcutaneously, particularly implanted inside the muscle fat skin tissue.…”

“…The authors have proposed CPW-fed monopole antenna design for implanted communication in the industrial, scientific, and medical (ISM) band at 2.4 GHz [4], which acts as a transmitting antenna in the proposed one-way communication link. To establish effective and efficient wireless links with the implanted antenna, the corresponding on-body wearable receiver antenna should be designed with unidirectional radiation characteristics, high gain, small size and low profile [5].…”

A novel coplanar waveguide-fed Z-monopole antennas are proposed for the first time for a industrial, scientific, and medical (ISM) band (2.4–2.48 GHz) applications. To make the designed antenna suitable for implantation, it is embedded in biocompatible Al2O3ceramic substrate. The antenna operates at resonance frequency of 2.45 GHz to support wide band communication for high data rate implantable neural monitoring application. The size of the antenna is 38.675 mm3(8.5 mm × 7 mm × 0.65 mm). The antenna was simulated and measured by immersing it in a phantom liquid, imitate the electrical properties of the human body phantom liquid. The simulated and measured bandwidths are 10.2 and 11.4% at the centre frequency. A study of the sensitivity of the antenna performance as a function of its dielectric parameters of the environment in which it is immersed was performed. The demonstration among the design EM characteristics of the antenna is presented by current distributions.

“…Polymers or plastic-based materials are becoming very popular for flexible antennas because of their robustness, flexibility, wettability, and stretchability. One such example is Kapton polyimide with a dielectric constant of 2.91, a loss tangent of 0.005, and high transition temperature (Tg), which is one of the most preferred substrate materials, for flexible antennas in the previous literature [ 71 , 72 , 73 , 74 , 75 ].…”

Arguably, 5G and next-generation technology with its key features (specifically, supporting high data rates and high mobility platforms) make it valuable for coping with the emerging needs of medical healthcare. A 5G-enabled portable device receives the sensitive detection signals from the head imaging system and transmits them over the 5G network for real-time monitoring, analysis, and storage purposes. In terms of material, graphene-based flexible electronics have become very popular for wearable and healthcare devices due to their exceptional mechanical strength, thermal stability, high electrical conductivity, and biocompatibility. A graphene-based flexible antenna for data communication from wearable head imaging devices over a 5G network was designed and modelled. The antenna operated at the 34.5 GHz range and was designed using an 18 µm thin graphene film for the conductive radiative patch and ground with electric conductivity of 3.5 × 105 S/m. The radiative patch was designed in a fractal fashion to provide sufficient antenna flexibility for wearable uses. The patch was designed over a 1.5 mm thick flexible polyamide substrate that made the design suitable for wearable applications. This paper presented the 3D modelling and analysis of the 5G flexible antenna for communication in a digital care-home model. The analyses were carried out based on the antenna’s reflection coefficient, gain, radiation pattern, and power balance. The time-domain signal analysis was carried out between the two antennas to mimic real-time communication in wearable devices.

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.
