Abstract : The rapid expansion of satellite communications and information and communications technology led to an increasing demand from end-users. Hence, services offering In-Flight Connectivity for airlines passengers are emerging. This work is focused on the implementation of accurate numerical models of large antenna arrays meant for this scope. After having put things into context and recalled issues linked to antenna arrays, numerical and experimental test vehicles are made, allowing to validate the modelling methodologies. Finally, the modelling of a large, dual circular polarization and wide-angle scanning radiating panel is addressed. This study then allows to estimate the performance of the panel function of steering requirements and possible dispersions from the active channels.
