Abstract
This paper presents a model to analyze the interference generated by a planar generalized array antenna placed on an aircraft. The antenna system analyzed is defined to work at K/Ka band (19.2-21.2 and 29-31 GHz) intended to be used for satellite communications applications with an asymmetrical geometry. The case study presented is focused on the interference produced at certain skew angles. The last can be translated as a misalignment between the line of the sub-satellite points of the GEO orbit and the local orientation of the airborne antenna. This analysis starts with the definition of the patterns cut that includes the direction of all the GEO satellites into the line of side to check the possible interferences including an estimation of unfavorable effects on adjacent satellites. This analysis is also performed taking into account the ESD (EIRP Spectral Density) mask provided in MIL STD 188-164B standard. Finally, different Beam-Forming techniques for the interference mitigation are also analyzed.
