ANTENNA SYSTEM, BASE STATION SYSTEM AND COMMUNICATION SYSTEM Russian patent published in 2016 - IPC H01Q23/00 

FIELD: radio engineering, communication.

SUBSTANCE: in an antenna system, the first antenna element array includes multiple antenna elements, and the same applies to the second antenna element array. The antenna elements are configured to receive and transmit signals in two different polarisation directions; the first combiner-splitter is configured to combine signals. The signals are received by the multiple antenna elements in the first antenna element array; the active module is configured to receive the signals combined by the first combiner-splitter in the two different polarisation directions, and perform frequency conversion on the signals combined by the first combiner-splitter to obtain baseband signals; the second combiner-splitter is configured to combine the signals. The signals are received by the multiple antenna elements in the second antenna element array; each second antenna apparatus corresponds to a pair of receiving channels, and the pair of receiving channels is configured to receive the signals combined by the second combiner-splitter in the two different polarisation directions; and the active module is further configured to perform frequency conversion on the signals received by the pair of receiving channels to obtain the baseband signals.

EFFECT: high network capacity.
