The radiation characteristics are analyzed by a hybrid method combining a full-wave method for near-field computation and an integral method for far-field computation. Results show that a deflected radiation field along the leaky rectangular waveguide can be obtained by properly designing the parameters of slots. This kind of leaky rectangular waveguide can be applied in rail transportation system, it will enhance the receiving signal and suppress the interference. As a result, the reliability of the system will be improved.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115858224","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 controlling leakage amount of each interdigital slot etched on the broadside of the SIW, the sidelobe level of the antenna can be reduced effectively. A four-way SIW power divider with Chebyshev current distribution in magnitude is proposed to improve the main lobe and to suppress the sidelobe. The simulated results show that both the gain and radiation efficiency are improved by using antenna array. The proposed CRLH antenna array has a sidelobe level of −13.3dB and a high gain up to 23.67dB at 5.8GHz.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115985882","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 numerical algorithms such as integral equation can be used for accurate simulation of monostatic radar cross section. However, the simulation of monostatic radar cross section is much more time consuming than bistatic radar cross section, if an iterative solver is used. In this paper we propose a scheme based on the adaptive cross approximation (ACA) and singular value decomposition (SVD) which can reduce the simulation time of monostatic radar cross section simulation using integral equation method.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116889001","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}

This metasurface can transform the incident plane wave into vortex beams carrying orbital angular momentum (OAM) in four different modes. This active metasurface is composed of an array of varactor diodes loaded unit cells. The transmission phase of each metasurface unit cell can be fully controlled by the capacitance of the varactor diodes. Thus, it can generate four modes of vortex beams separately by simply changing the transmission phase distribution on the metasurface aperture. The properties of the proposed active metasurface is demonstrated by simulation results and have a good agreement with the theoretical design.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420763","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}
