The ever-increasing demand and need for high-speed communication have generated intensive research in the field of fifth-generation (5G) technology. Sub-6 GHz 5G mid-band spectrum is the focus of the researchers due to its meritorious ease of deployment in the current scenario with the already existing infrastructure of the 4G-LTE system. The 5G technology finds applications in enormous fields that require high data rates, low latency, and stable radiation patterns. One of the major sectors that benefit from the outbreak of 5G is the field of flexible electronics. Devices that are compact need an antenna to be flexible, lightweight, conformal, and still have excellent performance characteristics. Flexible antennas used in wireless body area networks (WBANs) need to be highly conformal to be bent according to the different curvatures of the human body at different body parts. The specific absorption rate (SAR) must be at a permissible level for such an antenna to be suited for WBAN applications. This paper gives a comprehensive review of the current state of the art flexible antennas in a sub-6 GHz 5G band. Furthermore, this paper gives a key insight into the materials for a flexible antenna, the parameters considered for the design of a flexible antenna for 5G, the challenges for the design, and the implementation of a flexible antenna for 5G.

“…Different materials are available to fabricate flexible RF circuits, such as paper 3 and textile. 4,5 But the most used are polymers, among which we can find polyimide (Kapton), 6 polyester, 7,8 and polydimethylsiloxane. 9,10 One concern of these polymers is that they are mostly derived from non-renewable petroleum resources, which means that using this kind of materials to manufacture flexible devices generates electronic waste that hurts our environment.…”

This article presents the realization of a bandpass filter on a flexible biopolymer substrate with a suitable fabrication process. We used copper adhesive tape and laser structuring to fabricate the filter based on a quasi-lumped microstrip structure. The filter characteristics are a central frequency of 2.45 GHz, a bandwidth of 20%, and insertion loss of 1.2 dB. It is demonstrated that the filter's performance remains almost constant under different bending, folding, and rolling conditions. The results show that the proposed bio-sourced polymer is a good candidate for flexible green electronics and wearable applications.

“…Indeed, many works have already been carried out to design double-band textile antennas for WLAN, WBAN applications [5,6]. These research works aim to analyze the propagation of electromagnetic waves caused by the antenna in a specific frequency band near the body [7].…”

“…However, these antennas presented, at least, one of the following problems: very narrow bandwidth, large dimensions, which make them bulky, significant radiation to the body (you cannot solve one problem by creating another), and stability of parameters when bending off-body antennas. As an example of wearable antennas, we can mention the monopole antenna that was essentially designed to solve one of the main weaknesses of microstrip antennas (limited bandwidth) which prevent high-speed communications [7]. However, issues driven by miniaturization remain an obstacle for communication systems.…”
