AI Technical Summary
Long-wave magnetic antennas are susceptible to electric field interference in a strong electric field environment, resulting in a decrease in reception sensitivity and signal quality, making it difficult to achieve effective electric field shielding.
The Faraday cage structure is adopted, and the Faraday cage is constructed through six independent comb-shaped PCB printed boards. The magnetic antenna assembly is installed in it. The electric field signal is effectively short-circuited with the comb-shaped structure and ground point to prevent the formation of a closed loop, thereby attenuating the electric field signal without affecting the magnetic field.
It effectively solves the problem of electric field interference of long-wave magnetic antennas in strong electric field environments, improves the antenna's reception sensitivity and signal quality, ensures the stability and reliability of communication, and reduces equipment failure and maintenance costs.
