Apparatus, system, and method of rotating a polarization of radio frequency (rf) signals

Abstract

For example, a polarization rotator may be configured to rotate a polarization of one or more Radio Frequency (RF) signals communicated by one or more antennas via a wireless medium. For example, the polarization rotator may include an input to receive a control signal; and a plurality of polarization-rotator cells switchable between a plurality of predefined states, for example, based on the control signal. For example, the plurality of predefined states may include a no-rotation state and a rotation state. For example, the plurality of polarization-rotator cells may be configured to transfer the RF signals between the one or more antennas and the wireless medium at the no-rotation state, and to transfer the RF signals with a predefined polarization rotation applied to the RF signals at the rotation state.
