By aggregating two channels in sub-terahertz band, the real-time data rate of the proposed link is double to achieve 31.2 Gbps (15.6 Gbps per channel). The measured SNR is 24.2 dB and 25.4 dB, and the BER is 1.8e-7 and 8.6e-8 for two channels, respectively. Meanwhile, 4-K video transmission is carried out in two channels which are all clear and free of stuck. The successful transmission of aggregated channels in this work shows great potential for future high data rate realtime communication.","PeriodicalId":117712,"journal":{"name":"2021 14th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125968117","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}

Compared to the fundamental mode TM101, the spherical cavities based on TM211 mode offer appealing advantages including a higher unloaded quality factor (Qu) and a larger size. The filter is designed for 3-D printing technique, and a larger size facilitates the fabrication process and allows larger tolerances in the printing process. The filter is designed to have a generalized Chebyshev response with a centre frequency of 205 GHz, a fractional bandwidth of 4.4% and a passband return loss of 20 dB. An extracted pole resonator is introduced to produce a transmission zero at 215 GHz, for improved rejection at the upper stopband. Simulation results of the filter show good performance, demonstrating that the proposed design could find useful application in the 3-D printed millimetre-wave waveguide filters.","PeriodicalId":117712,"journal":{"name":"2021 14th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132416380","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 grooved-wall horn antenna has a pair of grooves on its wall to serve as an inbuilt polarizer. By connecting the grooved-wall horn to an orthomode transducer (OMT) in such a way that the pair of grooves is aligned at ±45° with respect to the horizontal and vertical polarization of the OMT, left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP) can be generated, thereby realizing a dual-CP antenna. High isolation is also achieved due to the low reflection coefficient of the horn and high isolation of the OMT.
