“…In the traditional wearable systems, battery and antenna takes large space. But due to the latest advancements in fabrication technologies, now days the size of the wearable computing systems are getting miniaturized and textile materials are being used in fabrication of antennas [7]- [8]. To increase the textile microstrip patch antenna bandwidth a number of ways can be used-by using a substrate of low dielectric constant, using partial ground plane, increasing substrate's height etc.…”

The aim of this paper is to investigate the possibilities of designing and fabricating a highly efficient and flexible wearable microstrip patch antenna operating at resonant frequency of 2.45 GHz. Copper Foil Tape (CFT) is used as a conducting medium in designing the patch and ground of antenna. While for designing the substrate, a graded profile based structures are made by combining two non-conducting fabrics i.e. Fleece-Curtain Cotton and Fleece-Polyester. The dielectric constant of these fabrics is measured with the help of ring resonator method. The proposed design models are simulated using CST simulator. To ensure the human body safety from antenna radiations in case of wearable applications, Specific Absorption Rate (SAR) is calculated on the simulated designs. Further some bending analysis of proposed antennas is also performed to ensure their applicability on different body parts like wrist, arm. Finally the proposed designs are fabricated and measured results are obtained using Agilent N5247A: A.09.90.02 VNA. TRL technique is used to calibrate the VNA with 3.5 SMA calibration kit.Simulated and measured results show good matching with each other in terms of resonant frequency, return loss, bandwidth and gain. The antenna designed using fleece-curtain cotton substrate achieved maximum bandwidth of 990 MHz, 2.22 dB gain and -34.99 dB value of S11 parameter. Voltage Standing Wave Ratio (VSWR) for all five antennas is less than 2. Hence the proposed antenna is a suitable candidate for wearable wireless applications.

“…Traditional methods of manufacturing antennas will not be able to provide the increasing request for novel applications as it requires both flexible and transparent antennas. The flexibility addition to these mentioned antennas ensures that it can be applied on the surface, which will not have planar geometry [43].The flexibility to such antennas makes sure that it can be used on the surfaces are not having planar geometry [25].…”

“…Wireless networking has shown different antenna architecture developments, such as meta-material antennas [127,128], fractal antennas [129], UWB and modular antennas [130,131]. Based on these conductive materials, two specific forms of transparent and non-transparent versatile antennas (see Figure 24) were tested by Kantharia et al [132] based on various criteria such as gain, return loss and radiation pattern. In contrast to the non-transparent antenna, a transparent antenna is inconspicuous and can be used in several technologies.…”

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.
