The probe not only has a wide impedance matching bandwidth, but also has no deterioration of the pattern of the interested frequency band. At the same time, the structure is simple and occupy small volume. The simulation results show that the impedance bandwidth of the probe proposed to this paper is 6-50GHz, and the isolation between the ports is more than 30dB in the whole frequency band, and it has good radiation performance and cross-polarization level. Therefore, this probe can find a scene in 5G millimeter wave frequency band measurement application, especially in multi-probe spherical near-field measurement system.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116221009","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 first approach uses a linear polarization interrogation with depolarizing tags able to reflect an electromagnetic signal with orthogonal polarization state with respect to the impinging one.

The two methods are described in terms of both conversion efficiency and performance at a system level. It is underlined that one of the main requirements for obtaining good performance of the chipless RFID system relies on the design of the reader transmitting and receiving antennas which should be wideband and guarantee a low level of radiated cross-polarization, together with a low-mutual coupling.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131170106","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}

In this preliminary study, the propagation constant and attenuation constant of the dielectric post-wall waveguide is rigorously calculated using our originally developed numerical method. The developed formulation is accurate and numerically very fast. Structural parameters of the dielectric post-wall waveguide are properly chosen in order to achieve the confinement of the field in the guiding region as strong as possible even in case of one-layered dielectric structure. The final goal of our investigations is to realize the functional dielectric post-wall waveguide-based filters, which are expected to have a practical application in THz region, where the metallic (PEC) rods are losing their properties.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132890930","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}
