  • ANTENNA SYSTEM HAVING ADAPTIVE POLARIZATION CONTROL
    Publication number: 20120162008
    Abstract: An antenna system includes: an orthogonal multi-polarization antenna configured to output independent double orthogonal polarizations through two independent input/output terminals; an antenna main control unit configured to perform a polarization control algorithm, collect and analyze information for polarization control, and provide polarization control information; and a polarization control unit configured to perform independent amplitude and phase control with regard to a pair of independent channels connected to the orthogonal multi-polarization antenna, based on the polarization control information received from the antenna main control unit, so that various polarizations are formed.
