In this resonator, a modified fractal “Sierpinski gasket” of three iterations was applied. Fractal elements “Sierpinski gasket” were made on a suspended dielectric substrate. The frequency spectrum of the resonator was investigated in the range from 10 to 40 GHz. The calculation of the main electrodynamic parameters of the resonator - resonant frequency, characteristic impedance, unloaded Qo factor - was made. The investigated resonator can find application in devices of the klystron type, which operate as amplifiers, generators, and frequency multipliers.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129793875","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 theory elements of these methods are considered, and examples of their application to field calculation in closed rooms are given.","PeriodicalId":277559,"journal":{"name":"2020 International Conference on Actual Problems of Electron Devices Engineering (APEDE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132074530","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}
