Abstract
Controlling an antenna's polarization sense. An antenna system includes a polarized antenna and a mechanism for controlling the polarization sense of the antenna. The controlling mechanism can include rotatable polarizer panels disposed between the antenna's aperture and the antenna's target. The polarizer panels are rotated to switch between polarization senses. The polarizer panels can comprise meander line polarizers that convert the polarization sense of a linear polarized antenna to a circularly polarized antenna and vice-versa. The meander line polarizers can be rotated from a position in which the meander line polarizer panels convert between linear polarization and right-hand-circular ('RHC') polarization to a position that converts between linear polarization and left-hand-circular ('LHC') polarization. The polarizer panels can be rotated using a mechanical system that rotates the polarizer panels based on a signal received from a remote device.
