The antenna consists of modified planar inverted-F antenna (PIFA) and a ground with a quadrate branch which is in the same side with PIFA. The impedance bandwidth is improved by dual-branch PIFA. Circular polarization is realized by modification of current distribution when a quadrate branch is added to the ground. Two PIFA structures are placed symmetrically on the diagonal of ground to realize dual circular polarization. The measured results show that the bandwidth of two ports in which return loss is less than -10dB is 1.22GHz~ 2.04GHz and 1.23GHz~2.05GH. The bandwidth for AR (axial ratio) <;3dB is 1.2GHz~1.95GHz with relative bandwidth of 49.2%. The isolation between two ports is larger than 17dB. The proposed antenna is suitable for mobile terminals in multi-mode satellite navigation for its wide bandwidth and compact structure.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124019140","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}

In traditional MoM, the calculation of the problem over a wide angle is implemented with iterative operations at a finer angle step, which must results to low efficiency. After applying CS technique to MoM results over any angles can be calculated with only several measurements. This method can be implemented by the following steps: obtaining measurements of induced currents by MOM with a sparse transform, and finally reconstructing the real induced currents by a recovery algorithm. Numerical examples showed that the results computed by CS could keep high accurate with low CPU time consumed.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685202","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 basic strategy followed in the proposed approach is to generate the desired solution of the periodic problem by first analyzing a truncated version of the same, and then predicting the asymptotic limit of the solution of the truncated problem by using an efficient extrapolation technique that needs to work with only a moderate-size truncated structure to generate the desired solution of the doubly-infinite periodic configuration.","PeriodicalId":421574,"journal":{"name":"2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115766031","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}
