Antenna system with adaptive polarization control

PURPOSE: An antenna system having adaptive polarization control is provided to improve the quality of a communications service by offering polarization characteristics of an antenna according to a wireless communications network adaptation unit per user or a sector user group. CONSTITUTION: An orthogonal dual polarization antenna(100) outputs independent double cross polarization. An antenna main control unit(300) provides polarization control information by collecting and analyzing information for polarization control. A polarization control algorithm is executed in the antenna main control unit. A polarization control unit(200) executes independent amplitude and phase control in regard to independent channel pair connected with the orthogonal dual polarization antenna according to the polarization control information provided from the antenna main control unit.
