TRANSCEIVING ANTENNA SYSTEM WITH CONTROLLED DIRECTIVITY PATTERN Russian patent published in 2012 - IPC H01Q3/30 

FIELD: radio engineering.

SUBSTANCE: system comprises antenna radiators, a receiving track with N receiving channels, every of which comprises serially connected low noise amplifiers and phase changers and is connected to a summator and an appropriate radiator, a transmitting track with N transmitting channels, every of which comprises serially connected power amplifiers and phase changers and is connected to a divider and an appropriate radiator, a transceiving device, a control device and a phase changer control device, outlets of which are connected with control inlets of all phase changers. Radiators are formed in the form of two phased antenna arrays, at the same time the receiving track is connected with the first antenna array, and the transmitting one - with the second one, and the outlet of the summator and the inlet of the divider are connected via a filter-diplexer with the transceiving device.

EFFECT: preservation of isolation between receiving and transmitting tracks excluding channel filters-diplexers from receiving and transmitting tracks with simultaneous improvement of weight and dimensional characteristics.
