A Comparative Study of Monopole and Microstrip Antennas for On-body Propagations Using a Dynamic Body Phantom Model

Human body motions can have a significant impact on on-body electromagnetic (EM) wave propagations and affect wireless body area network (WBAN) applications. A dynamic human body phantom model is used to study the effects of human body motion on on-body antenna performance. A monopole and microstrip antenna are placed on the human body phantom model and on human volunteers and antenna transmission (|S
₂₁
|) and reflection coefficients (|S
₁₁
|) are analyzed, showing similarity between the phantom model and human measurement and allowing for comparison of monopole and microstrip antenna performance during motion.
