Abstract:
A system and method for selecting a polarization for a particular antenna in an antenna array is disclosed. The system comprises an antenna array, wherein each antenna is adapted to receive and transmit horizontally and vertically polarized signals. The system also includes a switching network that is adapted to select the vertical or horizontal polarized signal for each antenna in the antenna array. The switching network also allows selection of a circular polarized signal from one or more of the antenna elements in the antenna array. This allows the AoX to be more accurate, as it is able to receive horizontally and vertically polarized signals, rather than just circular polarized signals, thereby improving its accuracy. The ability to receive circular polarized signals may be beneficial during reference periods to acquire the proper gain and frequency.
