Initially, a transverse slot is loaded to the radiating patch so as to reshape current distribution of high-order mode and suppressed its sidelobe radiation. Then, a U-resonator is introduced to improve the radiation performances of the resultant antenna. It can not only differentially feed the patch with single input to suppress the even modes of the radiating patch, but also generate an additional resonant mode to obtain wider bandwidth. The simulated results show that the proposed antenna can achieve an enhanced bandwidth of 60% and improved radiation performance with flat gain response in the working band.","PeriodicalId":143802,"journal":{"name":"2021 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"41 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120929466","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}
