  1. Hyundai MOBIS Automotive Group Improves EMC Analysis Process To 3D Using FEKO For Shielding Effectiveness Simulation

    Hyundai MOBIS, an automotive group affiliated with Hyundai Motor Group, produces a range of core automotive components and products for Hyundai and Kia companies, and other auto makers worldwide. In this case study, Hyundai MOBIS planned to better understand and improve the effectiveness of shielding enclosures that protect against illumination from both external fields and EM leakage from electronic products in the presence of apertures and slots used to accommodate visibility, ventilation, and access to interior components.

  2. Using Altair FEKO To Facilitate Development Of The World’s Smallest TV Antenna

    In Mexico and many other countries, television has become one of the most important forms of communication. The challenge usually comes down to the successful transmission of signals to more remote areas, especially indoors. At the Universidad Autónoma del Estado de Morelos (UAEM), Dr. Tecpoyotl’s team of students and researchers have developed an antenna that is miniaturized into a smaller footprint, while improving signal stability. This case study presents the success that the university had using Altair’s FEKO to facilitate the development of the world’s smallest TV antenna.

  3. Different Techniques For EM Design And Verification Of Large And Complex Structures: Industrial Case Studies

    New technologies in sensor design (AESA), and the need for integrated structure design to meet increasingly stringent RCS requirements, require a new approach to the problem, and the development of dedicated tools for analysis and processing. IDS addressed these problems with consulting activities leading to the development of dedicated solvers, procedures, and processors suitable for EM modeling of large and complex structures. In this presentation, IDS’ capabilities will be demonstrated in a naval environment case study which has been extended to other application areas.

  4. 5G In Perspective: A Pragmatic Guide To What’s Next

    The world’s communications and other connected technologies are evolving rapidly toward 5G in the hope of bringing about new and exciting solutions for deep learning, artificial intelligence, and “ambient awareness.” While these applications all share an LTE backbone, there are different requirements driving unique solutions, which broadens the LTE content space. LTE is the best global, scalable, and secure communications network capable of providing individuals, communities, corporations, governments and countries with tools to grow their own innovative platforms and initiatives. This paper examines the current state of LTE networks and the ways it could evolve to deliver a gigabit-per-second user experience, especially within emerging 5G systems.

  5. Multicast ABR, DVB-S2X, GSE, Time Slicing: Enabling Cost Effective Delivery Of Live Video Streams Via Satellite

    Many satellites are used to provide infrastructure for live broadcasting to large geographical areas. However, the bandwidth resources are expensive and unfit for delivering unicast content, which requires resources that grow linearly with the number of users, making the use of satellites seem an impractical solution. This, however, is not true with the latest satellite transmission progress (DVB-S2X and its ingredients) and a multicast approach. This white paper explains how satellites may be used to deliver live content to a wide range of connected devices in a way that is transparent to the existing components through the use of to Broadpeak’s technologies and TeamCast’s up-to-date features of satellite products.

  6. The Picture Of Dorian Array - Part 1: The Synthesis

    What exactly is needed for designing the ideal array for your application? Surely, you don’t have to go as far as selling your soul! In fact, all that is required is the right toolkit to optimize each phase array of the design workflow. This article is the first chapter in a series discussing the steps in designing an array.

  7. 3D Mapping System Helps Engineering Firm Efficiently Install IBW in Seattle Schools

    Engineers responsible for designing and installing In Building Wireless (IBW) networks have longed for tools to help them do their jobs better and more efficiently. For one engineering firm in the Pacific Northwest, utilizing the Anritsu LMR MasterTM S412E handheld analyzer with the MA8100A TRX NEON Signal Mapper provided them with considerable advantages over traditional signal mapping methods that require a GPS signal, which is usually unreliable – at best – or more commonly unavailable indoors. By using this innovative system, the engineering team completed the project faster so schools could open on schedule.

  8. Agile Product Development Through The Dovetail Connector Series

    The Dovetail Connector Series from Smiths Connectors offers a configurable solution for solving problems that require a greater degree of connector performance and customization than most connector suppliers can offer. This white paper describes the value, characteristics, and applications of Dovetail connectors, and discusses how designers can learn to take advantage of this technology to be faster, more innovative, and deliver more value to their customers.

  9. A System Based On A UAV Platform For Broadband Measurement Of High Intensity EM Fields

    Electromagnetic emission intensity measurement is of interest in both civil and military applications, as well as is the use of UAVs (Unmanned Aerial Vehicles) for auxiliary tools in the armed forces and in public security activities. This article describes the “PLASTIc” (PLatform Agnostic Sensors for opTImised design of midlife ship refitting) research project and its effort to combine the ability to measure high-intensity electrical fields with the taking of pictures to enable creation of an accurate CAD model reconstruction of naval systems.

  10. How To Make Radiated Emissions Measurements

    This article presents a step-by-step process of measuring the ambient field strength values in a radiated emissions measurement.
