The frequency response characteristics of planar frequency selective fabrics (FSFs) with cross-shaped units

Abstract

In this paper, a computer-based carving experiment was conducted to make frequency selective fabrics (FSFs) with cross-shaped units. Different samples with varying frequency selective fabric types, structure parameters, conductive layers, base fabrics and unit shapes were prepared and the transmission characteristics were tested using the Shielding Room Method. The reflection characteristics under different electromagnetic (EM) wave incidence angles were also tested to study the angle stability. Experimental results showed that in the given frequency range of 4–14 GHz, two types of frequency selective fabrics had good complementary transmission characteristics, with ideal bandwidths and resonance peaks, and the aperture frequency selective fabrics showed certain stability to small electromagnetic wave incidence angles. Structure parameters played a very important role in determining frequency response characteristics and base fabrics with different effective dielectric constant could also exert a great influence. However, the change of electrical conductivity within a certain extent would not affect the transmission characteristics and related work should be continued to explore the effect rule. Through rational control of the unit shape to increase or decrease the conductive material mass, broad-spectrum shielding or passing-through properties could be obtained. In the paper, the experimental results were discussed and analyzed in detail aiming at different parameters, and internal causes were further investigated, which could provide reference values for the relevant design and product development process.
