FIELD: airborne radar antennas.
SUBSTANCE: radiator, excitation line, and loop coupler are produced and mounted in position; antenna is made in the form of linear array in L wave band disposed in helicopter lifting rotor blade which is used as directivity pattern scanning mechanism due to its rotation.
EFFECT: enhanced mean radiation power in radiated wave band affording energy passage in atmosphere under severe weather conditions without noticeable attenuation.
