The proposed antenna etches four coupling slots on the antenna ground, four uniform coupling strips are made on the top layer of the antenna ground, the coupling strips are used to feed the radiation elements. Each coupling slot delivers the input energy to the corresponding coupling strip above it, every coupling strip excites the two adjacent radiation elements simultaneously. The presented stacked patch antenna is devised as a completely symmetric structure, resulting in simple structure and high isolation. The proposed antenna operating at 5.8 GHz, simulation results reveal that it has high gain of 9.6 dBi, low coupling of 22 dB and low profile of 0.056λ0.","PeriodicalId":141204,"journal":{"name":"2021 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115436848","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 wide foot matching layer is placed on top of the antenna, and T-slots are added on both sides of the Vivaldi opening to increase the resonance point and widen the bandwidth. This unit is formed into an array, and the array takes the form of a uniform planar array.
