“…The wearable antennas operating in dual-bands can be realized for WBAN applications on a solitary device which offers benefits of low-cost and space saving. In this context, numerous dual-band wearable antennas have been demonstrated on textile and flexible materials [67][68][69][70] as depicted in Figure 9. In reference 67, a dual-band wearable textile antenna based on 4 × 4 metasurface unit cell array was demonstrated as shown in Figure 9A.…”

“…In reference 69, a dual‐band flexible LoRa wearable antenna was demonstrated on polyimide substrate as shown in Figure 9C for ISM band applications. The lower band (.433 GHz band) is excited by embedding a pair of helical structure in radiating patch and upper band (2.45 GHz band) due to a pair of cross‐shaped slots on the ground plane.…”

The wearable technology and flexible electronics have been convoluted in modern technologies and many of applications especially insensors, biomedical, displays, solar panels, glasses, smart cities, integrated circuits, and wireless body area network (WBAN). They offer capability of mechanical deformation conditions mainly stretchable, bendable, foldable features and capable to severe environmental conditions. Nowadays, a device having lightweight, low‐profile, compact in size and flexible deployment on the system platforms is preferred. With the flexibility in the design of the antenna, they require flexible, robust, easy to wear, visually imperceptible, unobtrusiveness, and planar material for the realization. The characteristics of the wearable antenna may vary according to the material conductivity and their optical transparency, substrate selection and their thickness along with permittivity opted for and mechanical deformation behavior. Generally, the textile material is utilized to design the flexible wearable antenna due to material flexibility which can minimize the losses and enhance the antenna performance. Conversely, the visually imperceptible and flexible material is utilized to design transparent wearable antenna due to appropriate trade‐off between conductivity and optical transparency of the materials. For diverse WBAN applications, the flexible, transparent, and wearable antennas are utilized. This paper elaborates the comprehensive review and the state‐of‐the‐art research on the diverse categories of the wearable antennas based on the substrate characteristics such as flexibility and transparency. In addition, it provides the broad investigation of the flexible and transparent materials utilized to design wearable antennas and different tissue layers with their dielectric properties to develop the human multilayer phantom model.
