The process of installing VHF and UHF antenna systems on civil aircraft (AIRBUS, ATR,..) and their operability certification phase are mainly carried out by campaigns of measurements on reduced scale models or even expensive flight tests. In the framework of the European IPAS (Installed Performances of Antennas on Aerostructures of the 6th Framework Program) project run in partnership with European industrial companies and laboratories, ONERA has developed multi-domain calculation methodologies for the numerical simulation of antennas and isolation diagrams that take into account the complete structures of the aircraft. The objective is, on the one hand, to propose a consistent and collaborative calculation procedure for the aircraft and the antenna manufacturers that ensures that industrial confidentiality is protected and, on the other hand, to guarantee large gains in accuracy and calculation time in the parametric study phase inherent in the search for an optimal installation of the radiating parts.
