In this paper, the proposed global simulation is capable of modeling and simulating all active antenna systems to address the issues of co-simulation. Briefly, these issues include the aspect of large radiating panels which leads to a large data flow, the trade-offs between high performance models and complexity to obtain accurate results, and the needs for information on the energy performance of the system. For these needs, the solution is based on a specific co-simulation, which is defined by the association of a high performance circuit simulator with numerical models for large radiant panels. This specific co-simulation allows taking into account the interactions due to the connections of the active channels with the corresponding ports of the radiating panel. Indeed, the active channels are modelled by behavioral models, which are defined by the load-pull characterization and are connected to the panel diffusion matrix. The load-pull characterization allows to predict the impacts due to the active impedance variations on the active channels performances. Then the global simulation is implemented in the MATLAB programming environment and allows to determine the impacts on the performance of the active antennas like total power consumption, radiation, overall efficiency ... Furthermore, the global simulation allows to perform a performance optimization of the active antennas which takes into account all interactions within the system.
