Effects of the fabric substrate on performance and durability of textile-embroidered dipole antennas

In this work, several fabrics with different composition and structure have been used as the substrate for production of wearable textile-embroidered dipole antennas. The performance antennas has determined by measuring their resonance frequency, return loss bandwidth. To determine durability fabrics, assessed before after subjecting to washing abrasion cycles. results revealed that woven presented a good fastness, even in having elastic fibers or low-crimp structures. all cases, was maintained 30 For cycles, substrates higher stability (measured crimp ratio) wear whereas variability observed lower stability.
