The slot array contains a new method to make use of the internal mutual coupling between slots to achieve the desired current distribution with low SLL in the H-plane. In addition, to realize Dolph-Chebyshev distribution in the E-plane, a power divider is presented, including the design of SIWs with different widths, SIWs with corners bent in arcs, and T-junctions with two posts for the sake of achieving phase compensation, wide bandwidth, and high power-dividing ratio at the same time. By adding two extra posts to control the imaginary part of the impedance, a transition from conductor-backed coplanar waveguide (CBCPW) to SIW with tuning flexibility is applied to feed the antenna. The 64-element SIW slot array antenna is operated at 24 GHz with the simulation result of SLL around - 18.1 dB.","PeriodicalId":132941,"journal":{"name":"2021 International Symposium on Antennas and Propagation (ISAP)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129713318","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 RFID tag chip is embedded near one end of the feeding strip and it is also shorted to the main ground through a via hole. The size of the circular slot can aid in achieving good impedance matching between the tag antenna and the chip.
