“…If the skin depth is less or equal than the thickness of the conductive coating applied to each filament, δ ≤ T c , the resistance per unit length of each filament can be calculated using (2), where (R/l) f denotes the resistance per unit length of each filament, ρ coat and σ coat are, respectively, the resistivity and conductivity of the material employed for the coating, and S f represents the area of the effective conductive cross section of each filament.…”

This paper presents a complete and enhanced description of a parametric characterization and an electromagnetic analysis technique in order to simulate complex woven structures for the design of wearable microwave circuits and antennas based on smart textile. On the one hand, the parametric characterization consists of achieving the mathematical models which describe the different patterns conformed by the threads of the woven structures. This characterization takes into account the possible deformations of the materials inside the woven structure. On the other hand, the electromagnetic analysis technique consists of studying the conductive or dielectric parameters which describe the materials from which the threads have been extruded, and predicting the electromagnetic behavior of whole woven structures using the already explained parametric characterization. For this purpose, three different, although electromagnetically equivalent, models of the involved materials are needed, which subsequently reduce the computational resources required in the simulations. As a result, the woven structures can be characterized from the involved threads and the electromagnetic behavior can be analyzed in order to design wearable antennas or circuits.

Based on the research basis of single-layer cross-shaped frequency selective fabrics, the electromagnetic transmission characteristics of double-layer and three-layer cross-shaped frequency selective fabrics were explored in this paper. The frequency selective fabrics with different multilayer structures and specific-sized conductive units were designed, and then prepared by the computer engraving method and tested using the free-space method. The results show that the single-layer sample is less affected by the polarization mode of the electromagnetic wave, while the effect of the incidence angle is slightly larger. For the frequency selective fabric samples with the same frequency selective surface layers, the frequency selective characteristics of the double-layer samples are more ideal than those of the single-layer samples, while the electromagnetic loss of the three-layer samples is large and the narrow-band transmission characteristic is weakened. For the frequency selective fabric samples with the complementary frequency selective surface layers, the double-layer sample mainly shows band-pass characteristics and the narrow-band transmission characteristics are better than the single-layer sample. The three-layer sample of ‘patch + aperture + patch’ presents band-pass characteristics, and the ‘aperture + patch + aperture’ sample generates resonance at multiple frequency points, but the resonance peaks are all less than –10.00 dB, meaning that the sample presents full shielding characteristics in the test frequency band. The equivalent circuit model was built to explore the electromagnetic transmission mechanism, revealing the fabric type and structure, and the conductive unit type and size will affect the equivalent impedance of the frequency selective fabrics, thus further influencing the electromagnetic transmission characteristics.
