Wearable Textile Antenna for On-Body Communication

Wearable textile antennas are compact micro-strip patch antennas fabricated on a flexible textile dielectric substrate. The proposed antenna operates at 2.45 GHz frequency, which is part of the Industrial, Scientific, and Medical (ISM) band. The antenna is designed using denim as a substrate and a copper strip as a patch. The denim substrate is chosen due to its low cost, flexibility, and ability to be integrated with clothing. The copper patch is designed to provide a compact and efficient radiating element. The proposed antenna is characterized in terms of its return loss, radiation pattern, and efficiency. The synthesis is performed in four stages, which involve designing, testing, and optimization of the antenna. The experimental results demonstrate that the proposed antenna has a wide bandwidth, good radiation characteristics, and high efficiency. The wearable textile patch antenna presented in this research paper provides a low-cost and flexible solution for on-body communication systems, which can be integrated into clothing and used in various applications, including healthcare, sports, and security. The design comprises an 80 x 84 x 2 mm3 microstrip line-fed portable textile patch antenna, a denim substrate with a 1.6 dielectric constant, which achieved a gain of 5.40 dB.
