Abstract:
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 20 mm and is mounted on the human’s chest, while the second one is backed by a 2 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, band-
width, 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.
