“…The proliferation of body-centric communications, a subcategory of wireless body area networks (WBAN), has encouraged researchers to focus on flexible wideband and ultra-wideband antennas. UWB antennas have significant features such as small electrical size, low cost, low power spectral density, and high data rate [ 146 ], and have found extensive use. Because of the lower spectral density, the antenna is less prone to interference with other signals [ 147 ].…”

“…In recent years, portable antennas have gained interest because they could be built into the clothes [45]. A new wearable UWB semi-circular slot antenna was constructed by Amit et al [46] utilizing (flannel, cotton, and jean) based textile materials. As a comparison, it was observed that the reflection coefficient with phantom based any fabric is higher than (10) dB, which satisfied the requirements of the design.…”

Wearable antennas have received a great deal of popularity in recent years owing to their enticing characteristics and opportunities to realize lightweight, compact, low-cost, and versatile wireless communications and environments. These antennas must be conformal, and they must be built using lightweight materials and constructed in a low-profile configuration when mounted on various areas of the human body. These antennas ought to be able to function close to the human body with limited deterioration. These criteria render the layout of wearable antennas demanding, particularly when considering factors such as investigating the usability of textile substrates, high conductive materials during fabrication processes, and the effect of body binding scenarios on the performance of the design. Although there are minor differences in magnitude based on the implementations, several of these problems occur in the body-worn deployment sense. This study addresses the numerous problems and obstacles in the production of wearable antennas, their variety of materials, and the techniques of manufacturing alongside with bending scheme. This is accompanied by a summary of creative features and their respective approaches to address these problems recently raised by work in this area by the science community.

“…The simulated operating bandwidth of 2.2 to 17 GHz is reported, and reduction in operating band is about 1.5 GHz due to the bending effect that is observed. The antenna with semicircular slot is designed, and the performance is analyzed with three different substrate materials such as flannel, cotton, and jeans 24 . Of the three substrates, the antenna using flannel has the best performance.…”

Wireless body area networks (WBAN) is used to measure patients' health conditions continuously. Different kinds of sensors are required to measure health conditions. When such types of antennas are used on the human body, they are flexible with the movements. The usage of wearable devices is currently increasing in the biomedical field. The presented wearable antenna is suitable for biomedical applications. The presented ultra-wideband (UWB) flexible parachute shape wearable antenna is fabricated on a jeans textile substrate. The prototype antenna has a À10 dB measured impedance bandwidth of 5800 MHz (7 to 12.8 GHz) with average radiation efficiency of 75.28%. The prototype antenna's size is 40 Â 40 mm 2 (1.32 Â 1.32 λ 2 0 at centre frequency 9.9 GHz) and a peak gain of 4.5 dB at 12.33 GHz. The fabricated antenna is suitable for biomedical applications in X-band frequencies and can be implemented with a low-cost manufacturing process. The radiating element is made by conductive copper tape. Muscle-equivalent phantoms are used to analyze the body effect on antenna performance. The radiation effect emitted by the presented antenna on the human body is calculated by the specific absorption rate (SAR) value. The maximum SAR value of the proposed antenna is 1.84 W/kg at 12.33 GHz. This leads to promising results for wearable applications related to remote health care monitoring, such as biotelemetry and mobile health with a sensor-driven approach.flexible antenna, low profile, textile substrate, ultra-wideband (UWB), wearable applications, wireless body area networks (WBAN) | INTRODUCTIONRecently, textile antennas for Wireless body area networks (WBAN) applications have been increased due to their essential features, including size miniaturization, comfortable design, robustness, and weight.
