Speaker(s): Christoph Maeurer, C.J. Reddy

Abstract: With the increase in connected devices and platforms (such as 5G, 6G, C-V2X, ADAS etc.), advanced computational electromagnetic (CEM) tools have become part of the product design cycle. Now numerical simulations can be performed to evaluate the effects of antenna design, placement, radiation hazard, EMC/EMI, etc. for wide ranging industry applications. Interfacing with propagation tools, system level design can be accomplished that includes operating environment of the devices for device connectivity and throughput. Advent of cloud computing and AI/ML, and convergence with CEM simulations made connected, smart device design faster with reduced time from concept to the market propelling productivity and innovation. This talk will focus on advanced CEM simulation tools that incorporate numerical methods, such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM), Finite Element Method (FEM), Finite Difference Time Domain (FDTD), Physical Optics (PO), Ray Lunching Geometrical Optics (RL-GO), and Uniform Theory of Diffraction (UTD). This talk will also focus on future trends in cloud computing for physics-based simulations and the emerging topics such as Digital Twins.

Title: Model-based system design for active electronically scanned array (AESA) and channel specific impairments


Tuesday, 16 July, 13:40 - 14:25

Speaker(s): Ayodeji Sunday

Abstract: Phased array technologies are gaining popularity at a rapid pace. This is largely due to the growing complexity of modern applications. The effective consideration of complete phased array performance becomes inevitable. This includes RF nonlinear & noise effects, Gain/Phase quantization, Monte Carlo variations effects on total beam quality, sidelobe levels, and effective radiated power. Also imperative are the dynamic system-level scenarios with algorithms for adaptive beamforming. However, the lack of confidence in their design flow makes designers/engineers lean towards a conservative, inefficient overdesign approach.

PathWave System Design (formerly known as SystemVue) provides system architects in Radar/EW, 5G and Satellite communications with the essential tools to evaluate phased array and beamforming subsystems, including RF, Digital, and Hybrid beamforming architectures.

In this workshop we will highlight the tools and techniques that engineers can easily integrate into their phased array workflow to design their next generation phased array with confidence.

You will learn how to:

  • Model phased array system channel-specific impairments.
  • Perform phased array trade-off study for cost-efficient design.
  • Analyse active loading and scaling.
  • Analyse load-pull effect.

Speaker(s): Lars Foged

Abstract: This workshop explores the dynamic synergy between numerical simulations, advanced diagnostics, and the integration of rapid measurements with simulations to optimize antenna performance and system functionality in real-world environments. This optimization relies on highly accurate mathematical models for radiating antennas, derived from physical measurements and processed through equivalent currents. Initially devised for precise diagnostics of antennas and arrays, this methodology has become crucial for bridging the gap between measurements and Computational Electromagnetics (CEM) tools, enabling meticulous evaluation of antenna placement strategies.

Participants will be introduced to recent technological advancements in equivalent current processing, emphasizing its application in both diagnostics and accurate source modeling. The seminar will demonstrate how the interplay of diagnostics, strategic antenna placement, and the integration of measurements with simulations creates a holistic methodology for advancing antenna development.

Speaker(s) (part III): Bette Fabian

Abstract(part I): The rapid development of satellite communication has led to a growing interest in active array antennas. In this talk, we will delve into the unique challenges of satellite communication testing and focus on active array antenna G/T (Gain-to-Noise Temperature Ratio) testing. We will discuss the technical considerations of satellite communication systems, including link budget analysis, DUT performance estimation, and G/T measurement. The importance of accurate and reliable testing for ensuring the performance and reliability of satellite communication systems will be highlighted. The talk will then focus on G/T testing, explaining its theory, importance, and practical test verification. By understanding the challenges and requirements of satellite communication testing, we can ensure the performance and reliability of satellite communication systems.

Abstract(part II): The wide frequency coverage of our Compact Antenna Test Range (CATR) system necessitates the use of multiple feed antennas due to the narrow bandwidth associated with traditional designs based on rectangular and circular waveguides. To address this limitation, we have developed a broadband feed antenna that significantly extends the typical bandwidth in terms of reflection coefficient, gain, and radiation pattern. Additionally, we have minimized the radar cross-section (RCS) of the feed to reduce measurement uncertainties when testing devices with high RCS. Our presentation will showcase performance results, which have been tested using the Rohde & Schwarz ATS1800C CATR-based compact 5G NR mmWave test chamber.

Abstract(part III): Given the increasing attention of Reconfigurable Intelligent Surfaces (RISs) for modern mmWave systems and future 6G applications, the assessment and evaluation of RISs becomes essential. After analyzing the state-of-the-art in the context of RIS test & measurement aspects, a novel 3-D capable Over-the-Air (OTA) test setup is presented. With the help of this setup, the reflection characteristics of a mmWave RIS can be assessed for various angles of incidence and feed antenna distances. Following a detailed setup description, exemplary reflection pattern measurement results of a pin-diode based RIS prototype, working at a frequency of 28 GHz, are presented. Subsequently, possible setup extensions are discussed and the suitability of the proposed setup for measurements with modulated signals (e.g. 5G New Radio (5G NR)) and end-to-end performance measurements, is pointed out. The results show that the proposed test approach is appropriate for the OTA characterization of RIS modules in the mmWave frequency range.

Title (part I): Non-parametric Shape Optimization for RF Components
Title (part II): Coverage Analysis of Private Wireless Networks in Industrial Environments


Thursday, 18 July, 14:20 - 15:20 (coffee break) 15:40 - 16:20

Speaker(s) (part I): Davide Tallini
Speaker(s) (part II): Ta Rodrigo Enjiu

Abstract(part I): Parametric Optimization of Electromagnetic Components is one of the “work horse” tools for electromagnetic engineers for more than 20 years. While modern manufacturing methods like 3D printing allow the production of designs with very complex surfaces, the traditional optimization techniques limit the number of used parameters to describe the geometry.

This seminar demonstrates recent improvements in CST Studio Suite optimization techniques as well as how to link SIMULIA’s Tosca non-parametric-optimization suite with the CST Studio Suite. After a short introduction to the principles of the non-parametric optimization, the entire workflow, starting with a parametric pre-optimization step followed by a non-parametric fine-tuning in TOSCA will be demonstrated in a live demo.

Abstract(part II): Digitalization and wireless connectivity are key enablers of the Industrial Internet of Things (IIoT), also referred to as the “Industry 4.0”. Private wireless networks and new standards like 5G enable strategies for more agile and efficient production lines, facilities and plants. The benefits go beyond the connectivity, which is why private networks is a topical subject for the communication industry.

In this presentation, we explore how simulation can be used to perform coverage analysis and extract channel information for the proper design of devices and the network for complex industrial environments.
