All-textile inspired-folded dipole antennas for on/off-body communications medical applications

Two textile-based printed inspired Folded Dipole Antennas (FDAs) are presented in this paper for health monitoring of Covid-19 infected patients. The first antenna has an overall size of 80 mm x 20 mm and is mounted on the human's chest, while the second one is backed by a 2 x 4 textile Artificial Magnetic Conductor (AMC) array structure and is mounted on a surgical mask that covers the human's mouth. The first antenna is designed to work at center frequency, bandwidth, and gain of 2.45 GHz, 116.6 MHz and-2.45 dB, respectively. The second antenna works at 2.4 GHz with bandwidth of 76.6 MHz and gain of 2.71 dB. The SAR results equal 0.524 W/ Kg and 0.255 W/Kg at 1 g and 10 g, respectively, for the first antenna and 0.0174 W/Kg and 0.0091 W/Kg, respectively, for the second one. The previous specifications of the two antennas enable them to be utilized in wearable applications and Wi-Fi services.(c) 2022 THE AUTHORS.
