A new method to analyze reflectarrays with rectangular patches is proposed. While the standard procedure has been to calculate the electric currents on the patches using e.g. a periodic Green's...
This paper concerns the EM-modelling of high-accuracy reflector antenna systems, and in particular of reflectors for space antenna systems. Recent modelling developments are exemplified ranging...
Kriging fitting, originally developed for geological exploitation, is here applied for fitting an expected pattern to noisy, irregular in-flight measurements of a satellite antenna...
An investigation on accurate analysis of microstrip reflectarrays is presented. Sources of error in reflectarray analysis are examined and solutions to these issues are proposed. The focus is on...
In-flight measurements of satellite antenna patterns are often given in a highly irregular grid and the data may be influenced by severe noise such that an accurate pat-tern determination is...
A higher-order inverse method of moments algorithm, employing smooth current and geometry representations, as well as a very noise-robust solution algorithm, was presented at last year’s ESA...
GRASP has for many years constituted the de facto standard in the space community for advanced reflector antenna modeling. The tool has furthermore found widespread use in the earth station...
The accuracy of various techniques for calculating the radiation from printed reflectarrays is examined, and an improved technique based on the equivalent currents approach is proposed. The...
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...
