Second, theoretical and practical results of proposed volume horn array antenna with slant polarization are presented. Third, some result of a novel extension of Munk's current sheet concept is proposed, where the ultrawideband array antenna dipole screened dipole element is substituted by more complicated subarray of dipoles that have different sizes and values of mutual coupling. This approach of ultrawideband radiating panel creation allows to achieve a wide scan angles in orthogonal planes in frequency range with coverage up to 7:1.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772023","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}
