Integration of antenna measurements in numerical simulations, based on the equivalent current technique, has been validated in previous activities [1–8]. A link, enabling the export of an accurate numerical model, derived from the measured antenna pattern, to a number of commercial Computational Electromagnetic (CEM) solvers has been created and validated [9–14]. The equivalent current processing...
Accurate numerical models of a given antenna can be derived from measurements using the inverse source technique [1–3]. Using this technique, measured antenna patterns can currently be imported and used as numerical sources in a number of commercial Computational Electromagnetic (CEM) solvers [4–9]. This method has been validated experimentally and the achievable accuracy investigated for both stand-alone...
Electromagnetic models of measured antenna can be accurately computed by the inverse source technique, implemented in the MVG software INSIGHT [1–5]. The measurement processing is based on the expansion of the measured field using equivalent currents [7–10]. A recently created link enable the INSIGHT to export the electromagnetic model to a number of commercial Computational Electromagnetic (CEM)...
In antenna measurements, test procedures and best practices, validated by comparative measurements, constitute widely adopted tools to determine the uncertainty and thus the achieved accuracy of a given antenna measurement. For numerical simulations, there are no equivalent standards or tools to determine the accuracy of the numerical modelling of the same antenna.
Well-established procedures are consolidated to determine the associated measurement uncertainty for a given antenna and measurements scenario [1–2]. Similar criteria for establishing uncertainties in numerical modelling of the same antenna are still to be established. In this paper, we investigate the achievable agreement between antenna measurement and simulation when external error sources are...
Computational Electromagnetics (CEM) solvers are important engineering tools in the characterization and optimization of antenna placement on large and complex platforms. The accuracy of the source representation has a strong influence on the simulation accuracy of such antenna systems. It is customary to use domain decomposition technique based on the near field description of the local domain in...
A truncation study is presented to assess the impact of theta truncation in a spherical near-field antenna test system. The study is relevant for antennas with broad beams in the plane of truncation and where antenna weight prevents alternate mounting options, while facility space limitations necessitate truncation.
CISPR 12 defines the outdoor test site (OTS) as preferred test site and states that an absorber lined shielded enclosure (ALSE) can be used if the results gained there match those obtained on outdoor test sites OTS. The investigation of real sites with a validation method as proposed in [5] is very time consuming. The comparison of real world data with simulation models shall show the feasibility...
Two time efficient simulation methods for the prediction of the conducted and radiated automotive EMC emission tests, respectively, are presented. To verify the correct prediction of the cable bundle model, a novel cable bundle test bench has been developed. It allows a fully automated network analysis with up to 32 ports. Several types of cable bundles are experimentally characterized under stochastic...
