This work is devoted to the problem of the effect of a powerful ultra-short duration electromagnetic radiation on the superconducting protection device as a load of antenna-feeder circuit of radioelectronic systems. The above device is used in the monitoring systems of the land surface to the benefit of agriculture, geodesy, mapping, monitoring of land and ocean surfaces, and, also, the atmospheric layers, remote control systems in engineering and industry related branches. This goal was achieved by substantiation of the approach to the description of the arbitrary antenna response to the electromagnetic radiation, using the antenna system frequency response. The most significant result is the offered approach to the relationship determination between the response of the arbitrary antenna to the radiation influence and its characteristics in a radiation mode. The sought relationship determination showed that, such characteristics of the antenna systems are the antenna input impedance and the complex normalized radiation pattern in the radiation mode at an arbitrary frequency. The significance of the results is in obtainment of the analytical relations to estimate the effect of the radiation under consideration on the device that is in superconducting, mixed and normal phase states. The peculiarity of the obtained results makes it possible to consider the antenna system coordination degree of the protection device based on superconducting thin film. Conversion of the radiation energy into the induced currents’ energy that is the basis for selection and structural calculation of protection devices of the radio electronic facilities against powerful electromagnetic radiation build upon microstrip transmission lines.
