Radiation investigation of the antenna array, taking into account vibration actions

A mathematical model of two-dimensional waveguide-slot antenna array radiation is proposed, which allows to take into account the three-dimensional nature of its deformations arising from external actions. The article shows the results of the study of the vibration actions on the design (structure) and characteristics of the antenna array radiation installed on a moving object in its typical frequency range and amplitudes. The influence of the arising deformations on the electrical characteristics of the antenna array is estimated.
