The development of the Electromagnetic Data Exchange (EDX) standard was initiated as a joint effort in the Antenna Centre of Excellence (ACE) and the European Antenna Modelling Library (EAML) project, respectively funded under EU-FP6 and ESA-TRP budgets. Since the end…

An analysis technique for improved modeling of a printed reflectarray is proposed. The technique is based on a periodic approach where periodicity is applied on an extended unit cell, which includes the actual elements surrounding the element under consideration. An…

This paper presents a method of analysing beam waveguide systems, based on Physical Optics and Complex Conical Beams. The analysis procedure for one reflector consists of calculating the field spectrum in the auxiliary input/output plane, expanding the field (spectrum) into…

This contribution deals with the problem of reconstructing the extreme near-field of an antenna starting from the field measured at a larger distance. The presented method has several applications, including but not limited to antenna diagnostics, suppression of spurious contributions…

Accurate fitting of the noisy irregular amplitude only main beam data is essential for the retrieval of the Planck space telescope geometry. Therefore, a novel two-step fit-ting algorithm which focuses on the spatial dependency of the in-flight measurements has been…
