A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...

This work presents an alternative wearable tracking system based on a low-power wide area network. A complete GPS receiver was integrated with a textile substrate, and the latitude and longitude coordinates were sent to the cloud by means of the SIM-less SIGFOX network. To send the coordinates over SIGFOX protocol, a specific codification algorithm was used and a customized UHF antenna on jeans...

To detect defects in woven fabric a reduced coefficient fabric space is constructed, for which the principal components representing row and column wise data distribution of the training fabric sub images are determined with the help of a novel singular value decomposition based method. The size of this reduced coefficient fabric space is suitably optimized by particle swarm optimization method...

Cotton fabric was grafted with a poly (acrylamide-co-itaconic acid) co-polymer via ceric ammonium nitrate (CAN) induced graft co-polymerization in an aqueous medium. The grafted cotton fabric was loaded with Ag nanoparticles by entrapment of Ag+ ions into a grafted polymer network, followed by borohydride reduction. The resulting Ag nanoparticle-loaded grafted fabric was characterized by Fourie...

rehabiliating bushehr historic fabric and paying to it as an important urban fabric through increasing capabilities and facilities is main concern. bushehr historical fabric can be the consequence of several factors the most important of which is the persian gulf and its past history as a national one. this fabric, is organic, dense, compact, having its own characteristics. one of its main prio...

Recently, mesh networking and blockchain are two of the hottest technologies in the telecommunications industry. Combining both can reformulate internet access and make connecting to the Internet not only easy, but affordable too. Hyperledger Fabric (HLF) is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. We evaluate HLF in a real produc...

This proposed work introduces the textile characterisation analysis based on effects of fabric thickness and dielectric properties using transmission line method for a wearable antenna. The return loss (S11) (S21) were analysed denim, felt Tencel in correlation with conductivity Computer Simulation Technology Rogers 5880as reference sample. By varying from 0.5 mm to 4 mm, optimum type can be id...

This paper presents the propagation of dual-band diamond dipole antenna on three various jackets. The jackets are purely fleece fabric with Shieldit patches top it. network analyzers flexible lossless coaxial cable used to measure communication antennas. experiment involves a man ideal body mass index (BMI) wearing by placing antennas It is observed that best on-body engineered jacket. 10 dB im...

In this paper, a frequency reconfigurable, conformal, durable, optically transparent, and unidirectional antenna design is demonstrated for the first time. design, continuous tuning achieved by integrating varactor diode in folded dipole radiator, which backed water-filled reflector to produce radiation pattern mimicking characteristics of microstrip patch antennas. The radiating component expl...
