SWCNT Based On-Body Antenna For Detecting COVID-19 Affected Lung Using 5G-Band

In this paper, a 5G on-body patch has been designed for detecting COVID-19 affected lung. A new material Single Wall Carbon Nanotube (SWCNT) is used to design the patch of the antenna. Copper is used to designing the ground and FR-4 (lossy) is used in the substrate. The antenna has a total thickness of 5.5 mm where the patch thickness is 0.5 mm, the substrate thickness is 4.5 mm, and the ground thickness is 0.5 mm. The total volume (length x width x thickness) of this antenna is 80 mm x 80 mm x 5.5 mm (35200 mm

). For detecting COVID-19, designed two human lung phantom body models such as a COVID-19 affected lung model and a non-affected normal lung model. The patch antenna and all the models were designed in CST Microwave Studio. All the dielectric properties and other valuable parameters of the antenna materials and lung phantom models were collected and used for designing the antenna and phantom lung models. The antenna's return loss (S

) is −27.498894 dB, gain is 3.007 dB, VSWR is 1.0880641, directivity is 6.007 dB, resonant frequency is 6.296 GHz, SAR 1.19 W/Kg, bandwidth is 1.8174 GHz and the efficiency is 61% in free space. In this pandemic situation, this antenna can be given a new step for detecting COVID-19 affected lung.
