Breaking Boundaries In Wireless Communication: Simulating Animated, On-Body RF Propagation

By Tarun Chawla, Remcom

In the design and development of wireless devices for body-worn applications, several technical challenges must be addressed to ensure reliable on-body RF propagation. Key factors include the materials used in the device, which can influence signal interference, as well as weight, comfort, cost, and compatibility with other system components. Additionally, the human body itself acts as a complex, dynamic part of the antenna structure.

Traditional methods like physical prototype testing and human RF engineering are often used to assess antenna performance, but they can require multiple iterations and may not capture all real-world complexities. RF propagation simulations empower engineers to test numerous real-world use cases in far less time, and at lower costs, than in situ testing alone. Additionally, simulations provide a powerful visual aid and offer valuable insights to improve the performance and design of body-worn wireless devices.
