Antenna system intended to provide two-way radios between the unmanned aircraft (UAVs) and ground station. It is applicable to management and obtaining information from unmanned aircraft (lighter or heavier than air), which utilizes circular polarization of the electromagnetic field of the antenna and manage dynamic beam-steering antenna depending on the current orientation of the UAV. The antenna system on board the UAV comprises three constituent elements (1x, 1y and 1z) continuing antenna coupled respectively with three inputs of a switch unit (2), the three outputs of which are connected respectively with three inputs of a preamplifier (3) whose outputs are connected to respective three inputs of the unit for phase shift and alignment of the receiving room (4 '), the output of which is connected to the input of the receiver (5), to a fourth input of the block (4') is switched output cruise control (7). The second triad of inputs of the switch unit (2) are included respectively three outputs of block phase shift and alignment of the transmission room (4 '), to the input of which is included the output of a transmitter (6), the second output of the autopilot (7) It is connected to a second input of the block (4 '). To the input of the seventh switch unit (2) is connected the output of the control unit (8) which is in two-way communication with the receiver (5) and the transmitter (6). |
