In theory, the size of FCSIW can be reduced by nearly 50% compared with the substrate integrated waveguide (SIW) with similar propagation and cut-off characteristics. However, this excellent size reduction characteristic has not been widely used in millimeter wave equipment. Therefore, a modified BM multi-beam forming network based on FCSIW is proposed. The multibeam forming network is composed of directional coupler, crossover and phase shifter. The overall dimension of the novel BM is 1.04λ0 ×5.54λ0, which is half smaller than the traditional single-layer BM size. The compact BM will be an attractive candidate for future 5G terminal applications.","PeriodicalId":306297,"journal":{"name":"2019 IEEE MTT-S International Wireless Symposium (IWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128503800","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 proposed antenna consists of a reconfigurable filter and a wideband antenna. In this design, a wideband band pass filter (WBPF) with high selectivity is presented by employing two-section coupled lines, a short-circuit stub, and two open-circuit stepped-impedance stubs. After adding a coupled line, the WBPF is transformed to a dual-band band pass filter (DBPF). A reconfigurable wideband/dual-band filtering antenna is obtained through the integration of the reconfigurable filter and a wide-band monopole antenna. The functions of the filtering antenna are controlled by the PIN diodes. The operating impedance bandwidth of the wideband filtering antenna is from 1.27 to 3.47 GHz, while the dual-band filtering antenna is from 1.25 to 1.88 GHz and from 2.84 to 3.24 GHz. Details of the antenna design are shown, and the simulation for the constructed prototype are also exhibited and discussed.","PeriodicalId":306297,"journal":{"name":"2019 IEEE MTT-S International Wireless Symposium (IWS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116779187","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}

An equal power divider is constructed with commendable isolation between the two output ports based on the spoof SPP-TLs targeting to divide the power of the spoof SPP-TL into two equal parts with the same ratio. In general, there exists big impedance mismatch between the input and output ports in a 3 port lossy network. For this purpose, a stepped-impedance section is co-designed with accurate precision near the junction of the splitter which comes up with excellent impedance-matching between the spoof SPP-TLs and the coplanar waveguides. The proposed splitter attributing ultra-wide bandwidth, low loss, compact length and well balanced performance is a strong contender on bases of its high capability and excellent utilization in advancing integrated plasmonic appliances in microwave and terahertz frequency regimes.","PeriodicalId":306297,"journal":{"name":"2019 IEEE MTT-S International Wireless Symposium (IWS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124590487","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}
