Abstract
Impedance and radiation characteristics of 2.45 GHz wearable antennas in close proximity to a human body are studied in this paper. Three rectangular microstrip antennas namely wash cotton antenna, polyester antenna and polyester combined cotton antenna are considered in this preliminary study. Each of these three antennas is assumed to be placed in the vicinity of human torso with an air gap of 1 mm between torso and antenna. In this study, the human torso has been modeled as a lossy medium of fluid with permittivity and conductivity close to human torso at a frequency of 2.45 GHz. The results obtained indicate that the wearable antenna can provide required impedance and radiation characteristics even when it is placed in the vicinity of human body.
