In　this　paper,　a　new　genetic　algorithm　method　to　optimize　the　frequency　selective　surface(FSS)　is　presented.　The　optimization　speed　and　definition　are　promoted　by　limiting　the　parameter　range　and　changing　the　genetic　basis.　A　new　cost　function　is　introduced　to　optimize　the　multi-frequency　of　FSS　by　multi-object　optimization　(MO).　The　cirque　element　was　optimized　by　the　optimization　method,　fabricated　by　the　selective　electroless　plating　on　fabric　and　measured　by　the　arch　test　system.　Test　result　proves　the　simulated　result　coincide　with　measured　result.　Result　shows　that　it＇s　possible　to　realize　different　optimizations　based　on　the　various　applying　by　this　method.
