Abstract

Flexible antennas are placed near or on the human body without having an adverse effect on it. Therefore, they must be comfortable, flexible and not contribute to discomfort. At the same time, they must have a small value of the tangent of the angle of dielectric loss (tan δε), a minimum absorption of electromagnetic power, the ability to withstand mechanical loads and have a small change in the complex dielectric permittivity in a wide frequency range. The aim of the study is to verify the possibilities of using spinel pigments as fillers in styrene-butadiene rubber composites applicable as substrates and insulating layers in flexible portable antennas for wireless communications. It was found that the filler used has characteristics that ensure good performance of the antenna, combined with an aesthetic appearance. The optimal concentration of the spinel pigment, which determines the best operational characteristics of the antenna, has been established.

将具有尖晶石结构的颜料用作填料的可能性以及含有这些颜料的基于丁苯橡胶的复合材料的性能
柔性天线放置在人体附近或人体上,不会对人体产生不良影响。因此,柔性天线必须舒适、灵活,不会造成不适。同时,它们必须具有较小的介电损耗角正切值(tan δε)、最小的电磁功率吸收、承受机械负荷的能力以及在较宽频率范围内具有较小的复介电常数变化。这项研究的目的是验证在丁苯橡胶复合材料中使用尖晶石颜料作为填料的可能性,这种复合材料可用作无线通信柔性便携天线的基材和绝缘层。研究发现,所使用的填料具有确保天线性能良好、外观美观的特点。现已确定尖晶石颜料的最佳浓度,它决定了天线的最佳运行特性。

期刊介绍: The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science. The Journal of Rubber Research welcomes research on: the upstream, including crop management, crop improvement and protection, and biotechnology; the midstream, including processing and effluent management; the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory; economics, including the economics of rubber production, consumption, and market analysis. The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines. Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
