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...
Inverse source or equivalent current/source method (EQC) provides an accurate near-field representation of any radiating device in terms of equivalent electric and magnetic currents [1–4]. Starting from measured near or far field data in any measurement configuration, this technique allows to determine an accurate 3D electromagnetic model, maintaining the near field (NF) and far field (FF) properties...
Placement analysis in complex antenna scenarios require accurate computational electromagnetic (CEM) tools. A fundamental requirement to achieve truthful results, is that the source antenna must be accurately modelled. However, in many practical cases, a full-wave representation of the physical antenna is unfeasible or unavailable in the format required by the desired CEM solver. This paper describes...
Electromagnetic analysis of antennas in complex scenarios require accurate numerical modelling solvers. A fundamental requirement to achieve truthful results is the accurate representation/modelling of the source antenna. However, in many practical cases a full-wave representation of the physical antenna is either unfeasible or unavailable in the format required by the desired computational electromagnetic...
This paper provides an example of a reverberant environment application. A metallic box in different configurations has been simulated with CST STUDIO SUITE™ and the calculated results have been compared to measurements.
A planar topology of multifunctional C-X band wide-scan array is analyzed, based on the class of the aperture-coupled stacked patches. Performance is aimed at achieving both wide-band and wide-scan capabilities. The theoretical and the technological aspects that affect correct design and effective realization of the array structure are addressed. In particular, possible improvements of the active...
The possibility of achieving new advantageous solutions of high-performance UWB wide-scan arrays is investigated here for typical C-X band applications. Original compact, low-profile configurations of phased arrays, based on the class of the aperture-coupled stacked patches, have been analysed, designed, and tested. The relevant results show very interesting features as concerns band and scanning...
