AI Technical Summary
The performance of antenna arrays for radar systems and other sensors used in vehicles can be degraded due to the accumulation of snow, ice, or frost. Traditional heating methods may interfere with the electromagnetic properties of the antennas, affecting signal transmission and reception.
Design a heater array that minimizes electromagnetic interference by patterning conductive traces on an antenna array and integrating it with a transparent substrate of the antenna array to ensure seamless functionality. Employ low-loss dielectric materials and frequency-selective surfaces to improve frequency transparency and thermal performance.
It effectively removes snow and ice, maintains the electromagnetic performance of the antenna array, ensures the integrity and efficiency of signal transmission, and avoids electromagnetic interference.
