The proposed set-up permits the extraction of angular information using a sectored antenna array configuration. In this paper, the potential capability of the sectored antenna array for DOA (direction-of-arrival) estimation is investigated. Measurements will be presented for an 8-element array in the 2 GHz band. The antenna array is characterised in terms of input return loss, array mutual coupling and azimuth complex radiation pattern. The issues concerning mutual coupling between the array elements is also discussed. Furthermore, the paper presents measurements made using the array with our parallel channel chirp sounder at UMTS frequencies to estimate DOA information.","PeriodicalId":360668,"journal":{"name":"11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005]","volume":"47 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134356088","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}
