Comparison of two generations of textile MIMO antennas at IHF

A wearable textile antenna is a field of big interest and is getting more market [2]. Despite the simple idea and structure of such technology, some chapters are still open for further research, e.g. substrates, feeding, washing ability... etc. In this paper a comparison of two dual-polarized wearable textile antenna generations is introduced. Other than simulation and experimental results comparison, materials and production technology used will be also discussed, showing the advantages and disadvantages of these technologies. Both antennas have been developed to operate in the industrial, scientific and medical (ISM i.e. 2.4 GHz - 2.5 GHz) band [1]. The experimental and simulation results will be shown and compared to those achieved with an old version of this antenna.
