Many of these application scenarios are in restricted space, and put forward high requirements for the beauty and concealment of the antenna. Here, we report an optically transparent dipole antenna made of silver nanowire-graphene hybrid conductive film with light transmittance exceeding 80%. The copper antenna and the silver nanowire-graphene antenna have the same structure based on polyethylene terephthalate substrate, and their structure size is 12 mm × 8 mm × 0.2 mm. The resonant frequencies of the antennas made of the silver nanowire-graphene hybrid film is close to copper film. The antenna made of the silver nanowire-graphene hybrid film exhibits the typical radiation performance of an ideal dipole antenna. At the same time, it realizes the peak gain of 0.1932 dBi with a bandwidth of −10 dB at 90 MHz. The results indicate that the transparent antenna would have great potential of practical applications in agriculture and smart homes.","PeriodicalId":227449,"journal":{"name":"2022 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125759240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
