Traditional design approaches utilize full-wave simulations that are extremely time-consuming and computationally expensive. Our approach uses the multiplication property of ABCD parameters of cascaded networks to design N-layer PSSs, which consist of M different variations of conductive patches. Following the proposed approach for designing an N-layer PSS, we only need to perform N × M full-wave simulations instead of NM simulations, which must be performed when the traditional approach is used. Our method’s accuracy is studied and validated; specifically, it exhibits a total percentage error of less than 6% for both amplitude and phase.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246110","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 antenna is mainly composed of a printed three-element Yagi-Uda antenna whose reflector is loaded with a slot in the middle. A microfluidic channel, filled with a movable liquid metal post and applied as a manipulating switch, is attached to the surface of the reflector. Due to the coupled connection between the radiating arms and liquid metal post, the slot can be shorted or opened by moving the post, leading to changes in the lead and lag of phases between the radiating elements. Thus, the radiation pattern of the antenna can be adjusted. The simulated results achieved by CST Microwave Studio® indicate that the direction of the maximum radiation can be changed by about 180°, and the antenna can operate at 2.4 GHz at two working states.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129181364","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}
