Numerical analysis of ultra-wideband propagation for body-centric communication

This paper presents a study on body centric propagation based on ultra wideband technology using a compact and cost effective wearable antenna through simulations and validated by indoor environment measurements. The body worn antenna is placed on the human body model and different scenarios are considered such as off-body, body-to-body communication with and without the presence of partition made of concrete that will lead to variation in the propagation phenomenon. Fidelity factor results related to the received pulse shows that in the presence of the wall partition and human body, the average fidelity decreases by 4–5 % in comparison to no-obstacle scenario having high fidelity (0.97–0.99). Average fidelity in the presence of human body only is 0.96, thus leading to a reliable communication link in all scenarios.
