Based on this precondition, a n-bit digital phase shifter concept is proposed. The n-bit (n=1, 2, 3) LCP-based reconfigurable reflectarray (RRA) at 0.34 THz composed of 30×30 elements has been designed and analyzed. The radiation patterns of the RRAfor beam scanning at 15° and 45° are presented. Compared with 1-bit RRA, radiation patterns, such as main lobe direction, gain and side lobe level of the RRA are significantly improved when n=2, 3. However, 2-bit and 3-bit RRAs show similar radiation patterns. Due to 2 bits RRA only needs 4 states, the structure of 2-bit RRA is more simpler, which indicates 2-bit RRA is a low-cost solution to THz beam scanning array.","PeriodicalId":146561,"journal":{"name":"2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133862928","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}
