The effect of moisture on the performance of textile antennas

Garments of the future tend to increase functionalities by integrating components such as sensors for monitoring. Materializing these wearable intelligent textiles systems revealed the need for imperceptible integration of off-body communication devices. Planar textile patch antennas were introduced and carefully studied. However, when integrating textile-based antennas that operate at a frequency of 2.45 GHz into a garment, attention should be dedicated to the influence of environmental relative humidity.
