Textile microwave substrates: Special types of 3D knitted materials

The paper summarizes the experience with the development, production and optimization of 3D fabrics, specifically 3D weft knitted fabrics, planned for the integration of electronic components. Attention is focused on the presentation of 3D fabrics general properties which are given by their structure, used materials and finishing. The technological possibilities of preparation of this type of fabrics are summarized and their limits are described in detail and possible application areas are outlined. The possibilities of surface treatment from coating, lamination to printing or embossing are presented in order to optimize the fabric surface for a given application.
