Frequency reconfigurable textile antenna using different conducting patch and fabric substrate for 2.45 GHz and 5.8 GHz

摘要

This paper discusses a reconfigurable textile antenna designed on different fabric materials. The antenna is made up of cloth that can be used for frequency reconfigurability. There is a need to implement reconfigurable textile antenna. Fabric materials used as a substrate for this antenna are cotton, polyester, and nylon. Copper adhesive tape, silver conductive ink, and conductive paper are available in the market and are used as radiating material in the design of the textile antenna. In this paper, antennas are designed for 2.45 GHz and 5.8 GHz with frequency switching between these two frequencies. Three switches are used for frequency reconfigurability. When diodes are in OFF state then the antenna is tuned to 5.8 GHz and when diodes are in ON state then it is tuned to 2.45 GHz. There is a deviation of approximately 0.5 GHz in tuning frequency for both the antennas as compared to the simulated result.
