“…Conductive polymers like polyaniline (PANI) [ 25 ], polypyrrole (PPy) [ 26 ], and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) [ 27 ] seem to be promising materials for flexible and wearable antennas. The low conductivity of conductive polymers was improved by adding carbon nanotubes [ 28 ], graphene [ 29 ], and carbon nanoparticles [ 30 ] ( Figure 3 ). Flexible antennas using graphene are promising due to their decent electrical conductivity and excellent mechanical properties.…”

“…Magneto-dielectric materials found applications in flexible wearable devices due to the size constraint those devices demand. In [6], a flexible magnetodielectric polymer-based nanocomposite layer covering a Kapton (tape) substrate was used to design a flexible antenna. The design achieved multi band operation and covered two frequency ranges: [1.8-2.45] GHz and [5.15-5.825] GHz.…”

A mathematical modelling, and a derivation of the main parameters of the Magneto -Dielectric materials (substrate) and their effect on microstrip patch antenna design is shown. The Magneto -Dielectric materials (substrate) is shown to miniaturize the antenna size and enhance the bandwidth when used in the design of the microstrip patch antenna. The progression of the foundational modelling starts with laying out the concepts of the ferrimagnetic materials in terms of their permeability and permittivity, the components of antenna miniaturization. First, a ground free elliptical microstrip patch antenna (GFDSEPA) is simulated for miniaturization purposes at the 900MHz cellular band. A size reduction of almost 50% as well as bandwidth enhancement (100%) is achieved by utilizing the GFDSEPA. More size reduction is achieved by employing the magnetodielectric structure; in this case the commercially available Rogers MAGTREX 555 substrate is used. Other performance parameters show comparable results between the antenna simulated based on dielectric only substrate and the one based on magneto-dielectric substrate. A comparison of the main parameters between the results of this work and other results in the literature is shown. The application of the microstrip patch antenna design in energy harvesting, by using a rectifier circuit, is shown. Layout scenarios of the energy harvester are proposed. The proposed layout of the energy harvester ensures practicality of the proposed design and assures correlation between simulation results and experimental results. Index Terms-Electromagnetic energy harvesting, microstrip patch antenna, antenna return loss, plane radiation, antenna gain, antenna impedance.

In recent years, wearable antenna design has grossed research interest amongst academicians and researchers due to its versatile application in body area networks for transmitting/receiving signals in sufficiently large areassuch as ICU, trauma centers in hospitals for biomedical applications at ISM (2.45 GHz) frequency range. A wearable antenna is highly flexible in nature making it popular and demanding. What makes it even more suitable for biomedical applications is its simple design methodology and ease of integrationonpatient's dress/clothes for antenna placement in wireless communication. This paper presents a thorough investigation of various antennadesign methodologies to design a flexible wearable antenna that can be mounted on textile material for body-centric wireless communication. The traditional antenna design uses non-flexible substrate materials (such as FR-4, RT duriod, foam, etc..) having medium to high dielectric constant. This results in generation of surface wave losses which reduces antenna transmission capabilities. Flexible wearable antennas, on the contrary, uses ordinary textile materials used as a substrate whose dielectric constant is very low thereby providingreduced surface wave losses. As wearable antennas are mounted on textile fabrics it is possible to use these antennas to implant them on patients' bodies(inside/outside on the clothes) for transmitting the patients' body parameters (such as body temperate, heart rate, etc..) measured using various sensors/transducers. In this paper,a thorough review of different types of substrate materialsused for designing flexible wearable antennas is done.
