Joint Electromagnetic-Circuit Modeling for Active Antenna Array Synthesis

This paper describes a joint EM/Circuit modeling methodology, dedicated to active antennas arrays, with theoretical and experimental validations. The EM model handles inter-element coupling, while the Power Amplifier (PA) model can take important mismatching into account. Both models are then coupled to form a joint approach for EM/Circuit simulation and then validated using an active array demonstrator. An originality of this work is the elimination of isolators between PA and antennas.
