FIELD: antenna technology.
SUBSTANCE: invention relates to the field of antenna technology, namely, to ultra-wideband antenna arrays. The expected result is achieved by the fact that an antenna array is proposed consisting of printed antenna elements made on the upper layer of a two-layer or multilayer dielectric substrate, representing a slit formed by a closed H-shaped electrical circuit with high resistance, the electrical circuits of which are connected galvanically by means of metal polygons, forming a single layer with slits, while multi-channel nonequilibrium divider/adder connected to antenna elements, is implemented in accordance with a series-parallel or parallel circuit.
EFFECT: expansion of the bandwidth of linear antenna arrays to double the overlap of the extreme frequencies at a step less than the wavelength of the upper band boundary.
