An iterative full‐wave method for designing bandstop frequency selective surfaces on textile substrates

Abstract

This work presents an investigation of frequency selective surfaces (FSSs), with cross dipole, square loop, and triangular patch elements printed on textile substrates which exhibit some advantages over typical dielectric substrates used in FSS structures, such as high flexibility, low weight, low cost, and ease fabrication. Among these advantages, flexibility is certainly the most important one, allowing the FSS geometry to be used in many microwave circuit applications. Simulated results are obtained using both an implementation of the wave concept iterative procedure and Ansoft Designer commercial software for comparison purpose. Furthermore, textile FSS prototypes are built and measured to validate the simulated results. Good agreement is reported between simulated and measured results.

Iterative Full-Wave Analysis of Mandelbrot-Inspired Fractal Patch Antenna on Textile Substrate for UWB Applications

“…The WCIP method is a full-wave iterative method whose formulation is based on the electromagnetic wave concept [9][10][11][12][13][14]. It is a method that has been widely used by many researchers worldwide in the analysis of different types of microwave circuits such as antennas, filters, and frequency selective surfaces (FSS), including printed circuits on textile substrates, as presented in recent studies [13,14].…”

“…Results for resonant frequency, bandwidth, radiation pattern, and VSWR are obtained using the Wave Concept Iterative Procedure (WCIP). The WCIP is a full wave formulation that has been widely used in recent years in the analysis and characterization of various microwave circuits [9][10][11][12][13][14][15].…”

Study of the Unit Structure in Frequency Selective Fabric Fabricated by U-Shaped Velvet

“…This research not only has an important scientific significance, but also has an practical value in the field of radar absorbing material, communication window, fabric antenna, flexible functional clothing and so on [11,12]. At present, domestic and foreign researchers have studied 2D FSF by screen printing [13,14], weaving [15], weft knitting [16,17], embroidery [18,19], selective chemical plating [20], ink-jet printing [21] or other textile processing.…”

“…Compared with the planar FSS, the U-shaped velvet FSF has a 3D design, which increases design parameters. The velvet FSF would have more flexible lightweight characteristics and more structure patterns, which a conventional FSS does not have [12,22].…”
