Analysis and synthesis of phased array antennas in the presence of electrically large and complex platforms via a hybrid numerical code

This paper presents a procedure of numerical code hybridization. It can be effectively used in a fast analysis and synthesis of the field patterns radiated from a phased array antenna. In particular, both low and high frequency methods are employed to simulate simultaneously the strong coupling within an antenna structure and its interactions with electrically large structure existed in its vicinity. Examples are presented to demonstrate the validity of this approach.
