TWO-DIMENSIONAL MONOPULSE ANTENNA WITH ELECTRONICALLY CONTROLLED BEAM Russian patent published in 2010 - IPC H01Q25/02 

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering and can be used in microwave antenna engineering as part of antenna arrays for different purposes. The device consists of a line of emitters, phase changers and a distribution system made from first type distributors whose inputs are connected to corresponding outputs of second type distributors whose inputs are respectively connected to outputs of main and additional microwave adders which are connected to each other on one differential input through phasing sections and a directional coupler. In each channel between outputs of the line of first type distributors and phase changers, as well as between phase changers and corresponding channels of the line of emitters there are circulators connected by their two arms. The third arms of the circulators are connected to splitters such that, signals from the line of emitters reach outputs of the splitters through the circulators. One input of the splitters is connected through additional phase changers to outputs of the line of first type distributors, and the other inputs are connected through other additional phase changers to outputs of a second independent distribution system. The first, third and fourth type distributors are made on hybrid balance elements in a parallel signal division circuit.

EFFECT: simpler design and provision for operation with only a single independent scanning beam.
