摘要

Ultra-wideband (UWB) interference pulses pose a significant threat to the reliability of microcontroller-based systems. This paper presents experimental results demonstrating the effectiveness of meander lines (MLs) as a protective structure. Radio system transmitting sensor data are subjected to repetitive UWB pulses (230 to 393 V) injected into various microcontroller pins. Without MLs, pulses induce the microcontroller lock, data corruption, and even damage of connected sensors. However, incorporated MLs significantly attenuate pulses, reducing the lock and ensuring reliable data transmission. Practical implications of MLs include the enhancement of the electromagnetic compatibility and reliability of microcontroller systems in environments with the UWB electromagnetic interference.
