A current mainstream phenomenon is the design of ground based and onboard multifunctional radio electronics complexes, which are based on new technical solutions, including the application of active phased antenna arrays. This boosts the functional integration of the system equipment. Depending on the tasks, such antenna systems contain from hundreds to several thousand active modules. In this regard, the probability of failure of the active module drastically increases in comparison with the passive phased array. In these circumstances, ensuring the efficiency of active phased antenna arrays is a paramount task. In this paper we discuss the influence of operating temperature on the radiation characteristics in active phased antenna arrays onboard spacecraft.
