Object of study - adaptive processes controlled reception of electromagnetic waves and digital signal processing array. Purpose - development of principles of construction and engineering ways of implementing intelligent antennas - advanced adaptive digital antenna arrays capable of automatically in real time to respond to the electromagnetic environment. 1. The method of neural networks and bee swarm conducted multivariable optimization topology dual-frequency antenna array for receiving navigation signals in the range of L1 and L2 GPS / GLONASS. Array consists of 10 microstrip radiating elements powered independently via coaxial probes. Lattice structure made by a two-layer printed circuit technology based on high dielectric substrate serial type TMM 6 (dielectric constant ? = 6) with a thickness of 3,125 mm and 6.25 mm. The top surface of the dielectric substrate foil with a thickness of 3,125 mm on corners squares with sides 120 and 94 mm are four radiating ring resonator for a range of L2 and four ring resonator for emitting band L1. Array, navigation system, adaptive antennas. Terms of the report: the contract. 252 171, Kyiv-171, st. Gorky, 180, UkrISTEI.
