The design allows the adjustment of arbitrary amplitudes for the radiating elements using a rotatable aperture. No electric feeding network is needed as the radiators are excited using the fundamental waveguide mode and the amplitudes are adjusted in a solely mechanical way. The toolkit is designed after an existing antenna toolkit made from rectangular waveguide elements but presents benefits in manufacturing, usage and costs. Furthermore the design is easily scalable to other frequencies.","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130954860","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}

A statistical model based on Lyon's 1969 work on acoustic response variance in rooms is shown to be a significant improvement over the Rayleigh statistics model for predicting the maximum expected electric field response in electrically small enclosures.","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125971620","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}

A two probe near field scanning system is employed to obtain the digital circuit emission signal and also the reference signal from a power supply cable. The presence of electric jitter on the measured waveforms has made the processing and synchronization of the measured data problematic. It is infeasible to apply waveform averaging directly on the oscilloscope in order to reduce the measurement noise therefore correlation functions of reference signals are calculated to obtain the delay between each pulse and then align them properly. This process does not address the problem of jitter within the waveform.","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123739396","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 scattering parameters between an antenna and the terminals of the transmission line network have been measured using a vector network analyzer and converted into the average squared magnitude of the coupled terminal voltages. Different configurations of the transmission line network have been tested, where the alignment, length, termination as well as the connection of the shield of certain lines have been altered, in order to analyze the effect onto the resonances of the network (with high amplitudes of the coupled voltage, worst case in terms of EMC).","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114082537","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 optimal payload performances drive an early design of RF filters and antenna placement. Once the satellite integration goes in advanced phase, the antenna replacement becomes costly and impacts timing. Sometimes the decoupling level requested between two antennas is challenging and has to be predicted and verified by very accurate and reliable modeling tools [3]–[9] with the aim to minimize and optimize the testing at satellite level due to accessibility issues and to schedule constraints. Scope of this paper is to show an effective approach to predict antenna coupling factors applying EM simulation tools on a real industrial case where a possible EMI risk between a very large SAR array and Data Downlink antenna in X-band was studied. The GALILEO-EMT [1] suite was applied in this activity that ended with a coupling test on a representative satellite Mockup designed by Thales Alenia Space Italia team in the frame of a Low Orbit Earth Observation Satellite qualification (i.e. COSMO-SkyMed, a program managed by the Italian Space Agency (ASI) and co-funded by ASI and the Italian Minister of Defence).","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114715491","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}
