One of the most attractive features of LHM is the amplification of evanescent waves. Using such a feature, it has been shown that strong surface waves can be excited near the boundaries of LHM slab with small loss. We investigate the possibility to enhance the resolution of dielectric objects using the LHM slab. The Born approximation has been used to solve the linearized inverse scattering problem. Numerical simulations show that better resolution can be achieved when the LHM slab is involved than those without the LHM slab. The study has demonstrated that the amplification of evanescent waves in the measurement data and inversion algorithm is the main reason for the super resolution","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76564719","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 extracted FSS is a series-resonant grid (SRG) described analytically in C.R. Simovski et al., (2005). By applying the available analytical idea of C.R. Simovski et al. (2005), doing some parametric studies and using some innovation, a novel AMC with stable properties is obtained for wide range of incidence angles and with very compact size. During the process, one must be careful that the AMC bandwidth (BW) should not stray very much from acceptable limits. The FSS of the finalized AMC structure is a novel SRG that can be considered as a modified version of the well-known Jerusalem Cross (JC-FSS). For analysis of the structures, the Ansoff's Designer (AD) software, which is an electromagnetic solver based on the method of moments (MoM), is used","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88030996","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}

A cavity is formed within the substrate of the patch to accommodate the LNA module. The built-in LNA enhances the antenna reception capability without adding external circuits. Hence, the resulting patch has the same footprint and thickness as ordinary passive patches. Simulations and measurements on prototype antenna indicate that the built-in LNA module imposes limiting influences on the antenna properties, which can be corrected by rescaling the patch, and is hence an attractive option for making small antennas with large gains","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88215943","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}
