In order to achieve an antenna with good performance in this band, based on improving the aperture-coupled-feed antenna structure, we introduce a high-impedance surface of microwave photonic crystal structure in antenna design. By novel structure and effective design idea, the antenna can maintain a high gain and has a better stability in a wider band. The size of the antenna will be reduced at the same time, so that the overall performance of the antenna will be more perfect. The experiment results show that the 2.45GHz-band reader antenna based on high-impedance surface proposed in this paper has good performance, and the novel structure and effective design ideas of the antenna have practical significance for the reader antenna design.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121166554","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 formalized descriptions of the component, including data and computing descriptions, are studied using the theory and method of category. The focus is the unified description of component computing (i.e. component function). The unified description of the component in a certain domain is studied by many different methods: (1) The model of the component data is constructed using the partial order category theory. (2) The component computing is presented by the morphism. (3) The component computing is described using category theories (e.g. limit, nature transformation). The goal is to establish the unified description system of components based on the category theory. Discussions are also presented to stress its importance in the automatic identification and assembly of the component.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116367693","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}
