The silicon-based MEMS filter has the advantages of high Q value and low fabrication cost. The design solves the problem of large size and low integration of conventional filters. The filter bank is heterogeneously integrated between silicon by means of four filters layered two by two on the top and the bottom. A through silicon via (TSV) method is used to conduct the RF signal from the upper or lower layer to the output of the middle layer. The size of this assembly is significantly reduced without compromising the out-of-band rejection. In addition, this module improves the inter-channel isolation of the filter bank to a certain extent due to the low reflection effect of the coupling between the silicon on the RF signal.","PeriodicalId":126964,"journal":{"name":"2022 IEEE MTT-S International Wireless Symposium (IWS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134477518","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 slim metal plates and the metallic screws are utilized to construct a pair of series resonators, which provide a high port isolation for the antenna. Owing to this proposed decoupling structure, only one radiating patch is needed and a compact dimension of $pitimes(0.25lambda_{0})^{2}times 0.06)lambda_{0}$ is achieved. The measured -10 dB impedance bandwidth is 3.21-3.52 GHz (9.2%). A measured port isolation better than 18.6 dB is realized in the operating band and the peak value achieves 44.1 dB. Measured efficiency is higher than 83 % and peak gain is about 6.5 dBi. Finally, a three-port antenna based on the same principle is proposed. Overall, the proposed two antennas with a compact structure, high port isolation and good radiation performance are suitable for MIMO application.","PeriodicalId":126964,"journal":{"name":"2022 IEEE MTT-S International Wireless Symposium (IWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128206999","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}
