Advances in EMC and Wireless Measurements: Half-Day Technical Workshop with Standards Updates

1. Innovative Robotic Antenna Measurements

Dennis Lewis – The Boeing Company, Seattle, Washington

Abstract
Traditional antenna test facilities are typically designed with a specific measurement application in mind, and as a result these facilities tend to be comprised of single fixed measurement geometry. However, modern antenna measurement ranges employing multi-axis robotic positioners provide a near limitless degree of re-configurability in terms of measurement types and scan geometries. This drives an ongoing need to evaluate each unique setup and application. This previously unimaginable flexibility offers new opportunities for the improvement of safety, measurement quality and reduction of measurement uncertainties. These new robotic systems are capable of acquiring large amounts of special data allowing for the implementation of advanced post processing techniques. Model Based Systems Engineering and Development (MBSE/MBD) approaches can be employed to dramatically reduce the time, effort and cost associated with the test development and validation phases of a given program. MBSE tools can also be used to optimize test configurations to greatly reduce measurement uncertainties and simulate measurements. This presentation provides an overview of how these engineering techniques are being harnessed during the implementation of a new dual multi-axis robotic antenna test system.

2. Art. 3.3 d, e f Radio Equipment Directive (RED)

Bart Scholten – Kiwa, Apeldoorn, The Netherlands

Abstract
As from the 1st August 2025 all wireless products subjective to the RED are mandatory to comply with articles 3.3 d, e and f of the Radio Equipment Directive (RED) 2014/53/EU. These articles are introduced to set a baseline level of cyber security for these products. Under this article, manufacturers have to make sure that the product for example does not bring any harm to the network and ensure that the personal data of the user is protected. In this presentation Kiwa will introduce the requirements under the RED and provide insights about the current status of product security.

3. Recent Advances in EMC Test Site Evaluation Using Advanced Antenna Measurement Techniques

Zhong Chen – ETS-Lindgren, Cedar Park, Texas

Abstract
Calibrating antennas and validating test sites are interdependent processes, as they both mandate accurate antenna measurements in their testing environment. Site VSWR, as specified in CISPR 16-1-4 or C63.25, is used as the figure of merit to qualify test site performance from 1 GHz to 18 GHz. In the CISPR method, the standing wave is measured by sampling scalar fields along several linear paths. However, in an effort to simplify the measurement, test data are severely undersampled. Time Domain SVSWR, as specified in C63.25.1 (1-18 GHz), was developed to address the undersampling issues. For above 18 GHz tests, new challenges emerge, such as the need to test more locations in the Quiet Zone (QZ) and to measure the receive antenna beam coverage. Cylindrical Mode Filtered SVSWR developed as a result, which is now under active consideration in the C63.25.3 (18-40 GHz) and CISPR 16 standards. Participants of the seminar will gain a deeper understanding on technical background (the whats and whys) of the evolution of the test methods, and how advanced antenna measurement techniques are used to help to solve the different technical challenges.

4. An Overview of the IEEE P2715 Guide for the Characterization of the Shielding Effectiveness of Planar Materials

Professor Davy Pissoort, KU Leuven Bruges Campus, Belgium

Abstract
An electromagnetic shielding material is any material used to make shielding enclosures, typically to shield electronic components, circuits and systems against incoming electromagnetic fields, and to reduce the emission of electromagnetic waves by a circuit or system. For most applications, the choice of the material for designing and manufacturing the shielding enclosure is based on the characterization of planar samples of the shielding material. Several techniques are available to measure the shielding properties of materials. The recently published “IEEE P2715 Guide for the Characterization of the Shielding Effectiveness of Planar Materials” provides guidance on the use of recognized techniques for the measurement of planar material shielding effectiveness. The guide describes the features and limitations of commonly accepted techniques for characterizing the shielding effectiveness of planar materials and provides a basis for comparing the techniques. This presentation introduces the P2715 standard and summarizes the methods currently available to measure the shielding provided by a planar material.
