The technology described herein relate to polarization adaptive wireless power transmission systems. In an implementation, a wireless power transmission system is described. The wireless power transmission system includes a plurality of antennas and control circuitry operatively coupled to the plurality of antennas. The control circuitry is configured to determine polarization information of a beacon signal received at multiple antennas of the plurality of antennas of the antenna array. The beacon signal is transmitted by a client device in a multipath wireless power delivery environment. The control circuitry is further configured to dynamically configure polarization information associated with each of the multiple antennas of the plurality of antennas of the antenna array to match the polarization information determined at respective antennas of the multiple antennas.
