As a result, it is confirmed that the reflectivity of -13dB at the incident angle ranging from 5 to 45 degrees and the shielding effect of -25dB at the incident angle ranging from 0 to 30 degrees are obtained for circularly polarized wave used in ETC system. Therefore, realization of proposed wave absorber can be clarified.","PeriodicalId":378939,"journal":{"name":"International Conference on Embedded and Multimedia Computing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133503229","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}

There are diverse factors which affect the RF characteristics of Bluetooth application, accordingly the research which can advance a performance of application by improving properties of the antenna is carried. In order to advance a RF performance as an interface of wireless PAN environment, a novel antenna is proposed to operate at both 2.45 GHz and 5.8GHz and provide sufficient bandwidth for lower ISM band in which Bluetooth operates[1], Wibro band and upper ISM band which will be served in the future. The proposed antenna is advantageous for MMIC and LTCC using CPW feeding method. The proposed antenna includes the present Bluetooth band and 5 GHz ISM band, for that reason it can be applied to various applications.","PeriodicalId":378939,"journal":{"name":"International Conference on Embedded and Multimedia Computing","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127371769","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}
