ANTENNA SYSTEM Russian patent published in 2014 - IPC H01Q21/24 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering. The antenna system comprises three electrical antennae or three magnetic antennae with mutually orthogonal polarisation on X, Y and Z axes, three multipliers, an adder, three balanced modulators and a three-axis accelerometer; receiving outputs of the antennae are each connected to the first inputs of the multipliers; outputs of the multipliers are each connected to separate inputs of the adder; the output of the adder is the receiving output of the antenna system; the transmitting input of the antenna system is connected to first inputs of the balanced modulators; outputs of the balanced modulators are each connected to transmitting inputs of the antennae; the sensitivity axes x, y and z of the accelerometer are parallel to polarisation axes X, Y and Z of the antennae, respectively; outputs of the accelerometer on axes x, y and z are each connected to second inputs of the multipliers and balanced modulators, connected to antennae polarised on axes X, Y and Z, respectively. Polarisation vectors of the antenna system for transmission and reception are automatically adjusted on the vertical independent of the spatial orientation of the antenna system itself, thereby achieving matched polarisation of antenna systems of the receiver and the transmitter spaced apart in the horizontal plane.

EFFECT: automatic adjustment of the antenna system on vertical polarisation with arbitrary spatial orientation of the antenna system itself.
