The antenna is designed based on the modification of the monopole antenna fed by a coplanar waveguide (CPW). The antenna, for the first time, is designed and fabricated on the MC package format to realize the integrated on-chip level circuit package antenna. Besides economical advantage of mass production and automatic assembly, the proposed design on MC material has potential benefit to the system-level board miniaturization and system-level manufacturing facility.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809869","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 band-notch of 5.1 - 5.8 GHz (VSWR >; 2) is easily achieved by inserting dual reverse split ring slots in the radiating monopole of the antenna. By properly adjusting the dimensions of the inserted slot, the proposed antenna revealed good UWB performance i.e. impedance bandwidth of 3 - 10 GHz with VSWR <; 2, accompanied by a band-rejection function (5.1 - 5.8 GHz) in order to avoid interference caused from the IEEE 802.11a band. Time domain response shows that the proposed structure exhibits a minimal and constant group delay (except for notch band) as needed for UWB application. The antenna is fabricated using FR4 (εr= 4.4) substrate having dielectric thickness of 1.59 mm with total size of 30×20mm.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126794737","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 methodology employed in the software is an efficient hybrid approach combining ray-tracing and the integral equation method. The integral equation method is employed for characterizing the transmitters/receivers and determining radiation patterns of receiving antennas in the presence of dielectric objects. The image based ray-tracing technique is used for modeling the interaction between transmitters and receivers within a given cabin. The developed hybrid algorithm has been validated by comparing the simulated results with those obtained by commercial software or measurement data. Good agreement is observed. The developed software allows user to predict various channel parameters such as narrow- and wide-band site-specific channel parameters, and large- and small-scale statistic channel parameters.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127826286","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}
