The impedance distribution at the individual sub-arrays is optimized to suppress the effects of corporate feed radiation and to achieve the required low sidelobe level (~20dB). Conventional planar feed design exhibited a distorted radiation pattern with second sidelobe level shooting upto -14dB. The proposed approach reduces the second sidelobe level and maintains nearly Gaussian tapered radiation pattern over the angle. Measured gain of the array is 21dB.","PeriodicalId":169237,"journal":{"name":"2013 IEEE Applied Electromagnetics Conference (AEMC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133602304","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}
