In our approach, a compact size is achieved by means of a meander line for current path enlargement as well as the two parameterized slits that introduce additional degrees of freedom helping to ensure good impedance matching. The antenna design is carried out using surrogate-based optimization involving variable-fidelity EM simulations. This allows us to simultaneously adjust all geometry parameters of the structure and reduce the antenna footprint while maintaining low reflection in the UWB frequency range.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115969512","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}

By incorporating active elements into two magnetic metamaterial SRRs, gain medium with positive loss, perfect losslessness and even negative loss can be tuned to switch the function of the active reflector among a perfect absorber, a perfect reflector and a gain reflector. The reflectivity of the tunable reflector can be tuned from -20dB to +15dB via three DC control channels.

There is an interesting transition of the dominant mode as the triangle changes from acute to obtuse, i.e., when the triangle becomes equilateral. When the vertex angle is greater than 43°, triangular waveguides have higher cut-off frequency than that of standard rectangular waveguide with the same-sized base, and they have lower cut-offs when the vertex angle is less than 43°. The characteristic impedance of an isosceles triangular waveguide is close to that of its associated regular rectangular waveguide. These new results offer guidelines for the design, fabrication and applications of the isosceles triangular waveguide.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133011722","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}

Most conventional approaches to characterizing spatial channels based on measured channel response data require either mechanically steerable directional antennas or multiple antenna systems at both the transmitter and receiver to resolve the directions of arrival and departure. Here, we show that when either the receiving or transmitting platform is moving with a constant velocity, as in the case of high speed rail, the channel measurement system can be simplified considerably by exploiting the manner in which the signal associated with a multipath component located at a given angle with respect to the direction of travel is Doppler shifted. Further, the accuracy and resolution of the spatial channel model that is so obtained can be improved greatly by collecting the entire range-Doppler history of the returns from a given scatterer and focusing them into a single point using techniques adopted from bistatic synthetic aperture radar signal processing. Fourier methods commonly used to process SAR data are not appropriate here due to the proximity of the scatterers to the transmission path. The back projection technique, however, is entirely suitable albeit at the expense of greater computational overhead.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116681808","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}
