The first one is a simple one layer rectangular patch with narrow (4.9%) bandwidth, given for reference purpose. In second construction dielectric-filled cavity is used for bandwidth enhancement to 10% Third antenna is further improved by application of optimized, wideband microstrip feed line width transition at cavity boundary. Several designs of the transition are evaluated with electromagnetic simulation considering their performance, complexity and resistance to manufacturing inaccuracies. The two-step gradual transition with moderate complexity and satisfactory performance is used in the third antenna design resulting with improved resistance to manufacturing inaccuracies and 12.5% bandwidth.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"2 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130654827","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}

We exploit auxiliary kriging interpolation models established in the vicinity of the nominal design in order to speed up the process of statistical analysis of the antenna structure at hand. Sequential approximate optimization is then applied to carry out robust design of the antenna, here, oriented towards increasing the yield (defined with respect to design specifications imposed on the maximum in-band axial ratio level as well as antenna reflection). Demonstration example of a planar CP antenna with two feed line stubs is provided. Despite a large number of independent geometry parameters, accurate yield estimation is possible at the cost of a hundred EM simulations of the structure, whereas yield improvement (from the initial value of 63.5 percent at the nominal design to 99 percent) is achieved at the cost of 300 EM analyses. Comparison with conventional Monte Carlo analysis is also provided.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132725624","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}

Furthermore the low-cost realization allows for the utilization of multiple of these novel reflectors, giving the unique opportunity to generate a test environment with virtual targets at defined angles.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134361007","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}

It is planned to be the place, where various experiments, related to creating ultra-short electron bunches and high gradient acceleration techniques, will take place. One of planned experiments — ARES — Accelerator Research Experiment at SINBAD — is a conventional S-band electron linac, accelerating ultra-short (single fs) electron bunches to energy of 100 MeV. To ensure proper and stable work of this accelerator, a high frequency phase reference distribution system needs to be designed, manufactured and tested. In this paper the concept of such system for SINBAD is presented. The design is based on authors' experience and knowledge gained during development of similar systems for FLASH, XFEL, REGAE and ESS-ERIC accelerators.","PeriodicalId":143491,"journal":{"name":"2018 22nd International Microwave and Radar Conference (MIKON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122394716","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 calculations and comparison showed that a few former and today's radio stations frequencies oscillate around the integer theoretical Schumann mode values, with the NRTF LaMoure signal being the strongest candidate for a global VLF standing wave creation.
