The article devoted to a fairly new direction – flexible phased antenna arrays, the emergence of which is due to the ubiquity of curved surfaces.
The purpose of the work is to analyze the features of constructing flexible antenna arrays and consider the technologies for their implementation.
The development of a large number of flexible antenna arrays makes it possible to produce flexible, stretchable, foldable, shape–changing, lightweight, thin systems.
The need for flexible phased antenna arrays is quite large and the practical results and conclusions obtained will allow them to be used as widely as traditional phased array antennas
