This necessitates the use of frequency multipliers on the generation side, and harmonic mixers to extend the frequency range of the spectrum analyzer. With these setups there are certain important parameters that should be taken into account and this will be discussed with reference to an example where a 450 MHz wide signal is generated and analyzed using test equipment.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"48 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129704485","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 antenna is a four-arm Archimedean spiral antenna. To effectively direct the radiation in the upper half space region, the spiral antenna is backed by a conducting cavity, which is peripherally filled by an absorber ring. Antenna radiates circularly polarized waves. The height of the surrounding cavity is only 7mm, which leads to an extremely low profile structure. The polarization purity and antenna gain are investigated over a wide frequency bandwidth of near 1 to 8GHz.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134411793","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}

Due to the anti-phase property, the reflected energy can be re-directed toward four quadrants and a null to appear toward the normal direction. To increase the bandwidth, checkerboard surfaces of different EBG structures on the same ground plane are proposed. Two different configurations of EBG structures are designed to realize the 180° phase difference, in order to achieve a wider band Radar Cross Section (RCS) reduction. The RCS of the surfaces are compared with those of the equal-sized PEC ground planes.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116517286","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}
