“…While these geometries hold promise in gain enhancement, they do present a challenge in fabrication due to their inherently space-filling nature. This complexity necessitates specialized manufacturing techniques [13][14][15][16]. Despite this drawback, their potential to significantly enhance antenna performance underscores their continued relevance in wireless communication technology research.…”

The paper introduces a fractal geometry utilizing an Octagonal Split Ring Resonator (SRR) hybrid DRA as its basis. The primary antenna consists of a conventional Octagonal patch, which is then scaled down by 0.5 in the first iteration and further by 0.25 in the second and then the DRA is utilized to enhance its performance. Remarkably compact at 6 × 6.2 cm, the antenna demonstrates effectiveness across frequencies of 5.1, 6.8, and 7.2 GHz notably; it maintains a gain above 3.3 dBi and directivity above 4.1 dBi in all operational bands. Analysis employing surface current and return loss substantiates the impact of the fractal design with DR. These simulations and measured results affirm the proposed antenna's suitability for robust C band wireless applications, offering promising performance in antenna parameters.

“…Another class of CP antenna specifically designed for wearable devices have been presented by different research groups [65], [66], [67], [68], [69]. Pathan and Karn have designed a flexible antenna printed on fabric with dimensions of 22 × 22 × 1.6 mm 3 using a fabric of (ϵ r ) of 1.6 for 2.45 GHz frequency applications in WBAN [65].…”

“…The antenna has a total bandwidth of 140 MHz with an axial bandwidth of 80 MHz around the designed frequency of 2.45 GHz. Vaezi et al have developed a 20 × 2.7 × 0.1 mm 3 antenna with more than 75% measured bandwidth around the design frequency of 2.4 GHz for medical body area networks (MBANs) [66]. This bowtie antenna on a phantom has produced an operating range of 1.5 to 3.5 GHz and it has shown measured efficiencies of 87% and 79% making it suitable for free air and on phantom respectively proving that it is suitable for MBAN applications.…”

In this paper, a comprehensive review of the wireless body area network is provided. A review of the WBAN architectures, standard network topologies, and WBAN communication protocols is discussed in detail. Also, the security requirements of WBAN, security threats and types of attacks, and authentications used in WBAN are discussed. The paper also includes very detailed coverage of antenna types, antenna designs, and flexible antennas used in WBAN with some design considerations and comparisons. Some new energy harvesting technologies, materials used for energy harvesting, and energy management are also discussed. Energy harvesting and power management is an ever-growing area of research. Despite the fact that there are many nanogenerator-based energy harvesting methods, the demand for more efficient energy harvesting mechanisms is ever-increasing. The paper has an extensive discussion of energy harvesting and power management methods. Subsequently, some reviews of recent developments in wearable sensors and novel materials for developing wearable sensors are discussed. Finally, the application areas of WBAN are discussed INDEX TERMS Body area network, network security, wireless communication protocols, wearable sensors, energy harvesting, WBAN, flexible sensors, IoT.

“…6 This choice also removes the use of external splitter and phase shifter. Scientific literature describes CP antenna topologies on a flexible substrate, mainly for medical applications [7][8][9] (skin contact or implantation) or wearable/textile, [10][11][12] as detailed in the recent performance comparison chart from Zahran et al 13 Unlike the previous work from different researchers that describe CP antenna for flexible application, this article presents the specific case of fully planar, low-cost, bowtie topology for IoT in ISM band. There are no use of shorting pins as in Yang et al, 7,14 no mounting on balun, no staked layers, 7,15 or through connectors.…”

This article presents the design steps of a planar circularly polarized (CP) bowtie‐shaped antenna for 2.4–2.5 GHz industry, science, and medicine band. Using these design steps, an antenna model is developed. The antenna design is extensively described, simulated, measured, and analyzed. The antenna is simulated using the HFSS software and produced by laser etching of copper on a low‐cost Taconic RF‐35 substrate. The presented method of this design is easy to fabricate and is tunable to different frequencies. The produced CP planar antenna has a size of 55 × 55 × 0.25 mm3, a measured axial ratio bandwidth ranging from 2.33 to 2.49 GHz, and a measured peak gain of 3.21 dBiC. The produced antenna is fully planar, compatible with the printing process and thus suitable for Internet of Things applications.
