AI Technical Summary
Technical Problem
Traditional radar antennas experience pattern jitter and imbalance due to surface waves, particularly at high RF frequencies, affecting detection performance and angle resolution accuracy.
Method used
The design incorporates a dielectric substrate with a metal block positioned in the polarization direction of the antenna, ensuring a distance greater than a coupling threshold to suppress surface waves and reduce pattern jitter.
Benefits of technology
This configuration improves the detection performance and angle resolution accuracy of radar systems by minimizing the influence of surface waves on the antenna pattern.
