Unlike conventional antenna array, the proposed array employs a novel differential via-wall feeding structure, by which it can have low cross-polarization in H-plane and symmetric radiation pattern in E-plane. The via-wall feeding structure can also enhance the bandwidth. Low-temperature co-fired ceramic (LTCC) fabrication process is adopted to realize this antenna at 13 GHz. The proposed differential antenna integrates easily with ready-made differential devices. The proposed design achieved the 10-dB impedance bandwidth of 10% and peak gain of 6.8 dBi. The simulated results also show that an excellent H-plane cross-polarization of less than -27 dB is obtained.","PeriodicalId":355180,"journal":{"name":"2013 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133767162","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 problems which can not be calculated due to the insufficient memory can be solved by Out-of-Core solving method, but it takes too longer time because the speed limit of the data reading/writing on the disk. To solve the above problem, parallel Out-of-Core computing method is proposed. In order to use the memory sufficiently and reduce the reading/writing time, block parallel Out-of-Core computing method is also presented. The radiation patterns of a monopole mounted on a metal column and a shipborne antenna model are calculated respectively. The solving time of In-Core solver and Out-of-Core solver with different numbers of blocks and using different numbers of processors are compared respectively. The results indicate that the method in this paper can efficiently solve the radiation problems of antenna mounted on electrically larger platform, the solving time is only 6.3 % more than the In-Core method's, and the calculation precision is not lost.","PeriodicalId":355180,"journal":{"name":"2013 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132013064","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}
