AI Technical Summary

⚠Technical Problem

Existing technologies struggle to achieve equivalent performance when replacing materials in microstrip filters, leading to frequency band shifts and performance instability.

⚗Method used

By obtaining the model parameters of the 3D model, we can perform 3D modeling, physical processing, simulation and testing to determine the difference between the actual working frequency and the simulation frequency, and adjust the relevant material parameters to achieve the same performance.

🎯Benefits of technology

After the material was changed, the three-dimensional model could be accurately determined, ensuring that the performance of the physical sample was basically consistent. This solved the technical difficulty of changing the material of the microstrip filter and realized the correction of frequency band offset.
