The proposed has -10 dB impedance bandwidth of 2.82 GHz at 60 GHz. The single antenna element presents excellent return loss of -65 dB at 60 GHz, high radiation efficiency of above 92.5 % in the whole band, and peak realized gain of 5.25 dBi. The radiation pattern of the antenna is stable in the whole band. The simulated 8 elements based linear array provides gain of 17.5 dBi and half power beamwidth of 8o in azimuth. The proposed antenna can be reconfigured at different resonance frequencies by altering the radius of the rhombus-shaped patch. The proposed antenna finds its applications for indoor industrial and factory automation operations in the unlicensed 60 GHz ISM band (IEEE 802.15.3c, 802.11ad and 802.11ay), as well as 60 GHz indoor localization.","PeriodicalId":106416,"journal":{"name":"2022 International Workshop on Antenna Technology (iWAT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124528951","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}
