WDEs are used for speed control of Reaction Wheels (RW). Four numbers of Reaction Wheels are mounted in tetrahedral configuration in the spacecraft. The combined vector of all the wheels obtained by varying wheel speeds is used to orient the spacecraft in orbit. The wheel speed and motor current parameters of these actuators are very critical signals as these are used to determine health of the Reaction Wheels thereby determining the pointing accuracy of the spacecraft platform. On these signals, spurious noise was observed to be riding during wheel operations. These noise signals were spike-like and minimum amplitude of 0.5 V. The process to locate the source of these noise signals and their mitigation is presented in this paper.","PeriodicalId":333702,"journal":{"name":"2016 International Conference on ElectroMagnetic Interference & Compatibility (INCEMIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121679478","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}

As the technology advances, there is a need to place large number of electrical and electronic systems into automobile vehicle. Few of these systems include Airbag inflator, Power Steering module, ECU with other module connector, Tire Pressure monitoring, Infotainment system, DC Motors, Ignition System and Electronic Braking System. Installing a large number of electrical and electronic systems into a very confined space poses the problem of EMI through Radiated and Conducted Emissions. This paper discusses about the investigation of Radiated Emission from Music infotainment System and mitigation techniques to reduce the radiations. Music Infotainment System has been investigated for Radiated Emission in ARAI Lab, Pune in the frequency range of 150 KHz to 3 GHz as per CISPR 25 Automotive standards. After investigation, the radiation level was found to be exceeded by around 8–10 dB at different frequencies. To mitigate the radiations, the Music Infotainment System has been shielded with specially designed Aluminum Enclosure and re-tested for Radiated Emission. It was found that the radiation level was reduced by around 10 to 12 dB. Hence with Aluminum Enclosure, Music Infotainment System was found to be Compatible with CISPR 25 EMI/EMC standards.","PeriodicalId":333702,"journal":{"name":"2016 International Conference on ElectroMagnetic Interference & Compatibility (INCEMIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124217522","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 array design is first formulated as an optimization problem with the goal of reducing peak sidelobe level to −50dB. The objective of the FPA algorithm is to determine the optimized set of amplitude excitation coefficients to obtain the desired pattern. The patterns are numerically computed for different array lengths and the results obtained are compared with those of conventional method in the present paper. These low side lobe patterns are useful to overcome EMI problems in radar system.","PeriodicalId":333702,"journal":{"name":"2016 International Conference on ElectroMagnetic Interference & Compatibility (INCEMIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129514603","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}

Radiation with desired polarization is required for several applications. Wave guide junctions can be used for such purpose. In general, Tee arm is coupled to main waveguide of H-plane Tee junction through longitudinal slot. To produce vertical polarization with purity, coupling can be done by an inclined slot in the narrow wall of main wave guide, which also provide additional parameters for the array designer. In the present work after determining the resonant length of slot, the analysis is made to obtain conductance, susceptance, coupling and VSWR as a function of frequency and antenna parameters like slot width and slot angle. The results are numerically computed for L-band H-plane Tee junction using the concepts of self-reaction and discontinuity in modal current. The data presented is extremely useful for the array designer.","PeriodicalId":333702,"journal":{"name":"2016 International Conference on ElectroMagnetic Interference & Compatibility (INCEMIC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122542968","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 structures have been built over a 53 mm × 50 mm × 1.6 mm FR4 epoxy substrate with a relative permittivity of 4.4 and a dielectric loss tangent of 0.02. The coaxial feeding mechanism has been employed. Simulations have been carried over HFSS v-15. The initially designed antenna resonates at 6.95 GHz and 7.2 GHz with respective reflection coefficients of −24 dB and −19.5 dB and a gain of 4.4 dBi and 8 dBi respectively. The bandwidth attained around 6.95 GHz is 160 MHz while that attained around 7.2 GHz is 160 MHz. The proposed structuremay be used for fixed satellite and mobile applications at 6.95 GHz and for fixed mobile and space research at 7.2 GHz. The modified structure has center frequencies of 5.56 GHz and 6.21 GHz that offer respective reflection coefficients of −21.1 dB and −21.2 dB with gain of 17.1 dBi and 11.6 dBi respectively. The attained bandwidths are 170 MHz and 290 MHz.
