The proposed design is employed for launching angular momentum (OAM) beams, as well as beam scanning applications. In the design procedure, the working mechanisms of the Vivaldi array fed-reflector are discussed firstly. Then, the design details of the Vivaldi array feed are analyzed, followed by the discussions of multi-mode OAM beams and scanning beam radiation patterns. Thanks to the inherent multi-beam abilities of the reflector, the 0-OAM-mode beam can be steered over a conical scanning range of ±10°. Moreover, the flexible excitations of the Vivaldi array feed provide more possibilities to superpose multiple OAM states simultaneously, which can enhance the spectrum efficiency and the channel capacity.","PeriodicalId":219295,"journal":{"name":"2023 IEEE MTT-S International Wireless Symposium (IWS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123512757","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}

The influence of radar bandwidth on imaging quality is studied by comparing the images acquired under different radar bandwidths.
