Abstract: |
Advanced antenna reflectors(such as polarization sensitive surface PSS and frequency selective surface FSS)are taken as examples, which can achieve frequency reuse, high sensitivity and low noise. The crucial technical problems and solving methods in the process of fabricating metallic pattern by laser ablation on composite antenna reflector are described, and actuality and development of 3D metallic film pattern and laser ablation technologies are also introduced. |
