The antenna is investigated using characteristic mode analysis to show that by loading the slots and using the curved trapezoidal shape, the high-order modes shift to the lower frequency enhance the bandwidth. Multi-square-slotted-ring unit cells are integrated as an artificial magnetic conductor that is located below the antenna to act as a reflector. The proposed antenna operates from 0.85 GHz to 3.7 GHz with an average gain and front to back ratio of 10.5 dBi and 19.5 dB, respectively.","PeriodicalId":257699,"journal":{"name":"2020 4th Australian Microwave Symposium (AMS)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116040746","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 single-ended-to-balanced power dividers are built based on slotline-to-microstrip transitions, which are able to provide high commonmode suppression and low differential-mode-to-common-mode conversion levels. A wideband differential circularly-polarized (CP) antenna array is designed fabricated and tested using the differential feeding network. The experimental results verify that the presented differential feeding network can be used in feeding differential CP arrays to achieve high gain, symmetrical patterns and a wide axial ratio bandwidth.","PeriodicalId":257699,"journal":{"name":"2020 4th Australian Microwave Symposium (AMS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131418437","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}
