Abstract
In order to respond the growing interest towards radio frequency identification textile transponders, the authors propose a new approach to design radio frequency identification (RFID) devices by introducing the RFIDtex concept. The coupling system of inductive loops is implemented in the textronic structure with the RFID interface in order to split the transponder into two independently manufactured components. Then both modules can be easily integrated into the RFIDtex tag. The presented simulation and measurement results prove the concept of manufacturing a relatively small antenna in the form of a meandered dipole sewn in with a single thread, and further, that can be connected to the RFID chip through the coupling system without galvanic junctions. The achieved parameters clearly indicate that the tag can correctly communicate with the read/write device as well as the coupling between its both parts works properly, and the impedance matching is possible in this case. The possibility of confectioning products with electronic identification tags at the textile factory site and improved resistance to the impact of environmental conditions are the main advantage of the proposed approach to the RFID devices designing. The RFIDtex transponder idea proposed by the authors was restricted in the patent no PL 231291 B1.

Summary
The idea of Internet of Things (IoT) is mainly disseminated through the use of wireless systems such as radio frequency identification (RFID). The RFID technology is becoming more and more popular in everyday life, it is still not sufficiently implemented in management and logistics processes of the textile industry. The major barrier of introducing automatic identification into the successive stages of the product life (i.e., production, logistic, storage, shipping, trade, service, usage, maintenance, utilization, etc.) consists in costs of its implementation. When looking at today’s market of RFID devices, designers have at their disposal incompatible concepts and systems dedicated to apply to a single stage of the mentioned product life. It is usually not economically profitable to implement an RFID system just only, for example, to improve production processes
