The antenna includes two parts, the metallic helix and the microstrip on the substrate for feed. The proposed antenna structure is well suitable designed by MEMS technology, the fabrication of the structure needs only one wafer, and the antenna can be easily integrated with other parts of on-chip circuits. The antenna is characterized by high gain (17.6 dBi) and wide relative bandwidth (44%) from 2.8THz to 4.4THz. There are many tunable parameters of the helix, so that high performance THz antenna can be achieved by optimizing these parameters. The proposed antenna can be manufactured by MEMS processing with low fabrication cost, suitable for many THz systems.","PeriodicalId":132755,"journal":{"name":"2016 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133307831","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}

Electronically tunable phase shifters as one of the key building blocks in sub-THz systems, especially waveguide based phase shifters, encounter difficulties in both design and fabrication. In this paper, an electronically tunable rectangular metallic waveguide with graphene integrated operating in sub-THz frequency is proposed and its phase modulation properties are investigated. It shows that a maximum 34-degree linear phase shift is obtained at 315 GHz with bandwidth more than 50 GHz, and the reflection and maximum insertion loss are lower than -15 dB and 3.5 dB in this frequency range, respectively. The phase modulation feature can be applied to design of graphene based waveguide phase shifters and other graphene based waveguide phase modulators.","PeriodicalId":132755,"journal":{"name":"2016 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123291940","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}
