Abstract：To enhance the wave-transparent performance atthe seams oflarge glas fiber composite radome panels n the X -band，this studyproposesanoptimization methodbasedonwiretuning.Byloading metal wiresontotheedgeribsof the radomeseams，thecharacteristicimpedanceofthematerialismatchedtoreducereflection，therebyachievinghightransmissionperformanceattheedgeribs.Fullwave electromagneticsimulationmodeling demonstrates that，within theoperating frequencyband，themaximuminsertionlossattheedgeribsdecreasesfrom3.0dBto2.5dBafteroptimization，resultingin a0.5dBimprovementinadometransmisionperformance.This methodfeaturesasimple implementation，lowcost，ndignificant performanceenhancement，making it widelyapplicable forimproving thewave-transparent propertiesof edge ribs in large radome panels.
