AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

A heater array that heats a sensor load in a vehicle is disclosed that is positioned directly on a sensor region of the sensor load along a path of sensed energy. This configuration provides direct heating of the sensor region, thereby minimizing the energy required to prevent snow or ice accumulation while reducing interference with operation of the sensor load.
