Abstract: A wind turbine blade comprising a system for monitoring the deflection of a wind turbine blade is described. The system comprises a wireless range-measurement system, having at least one wireless communication device located towards the root end of the blade and at least one wireless communication device located towards the tip end of the blade, the communication devices comprising antennas polarized substantially perpendicular to the suction side of the blade and substantially parallel to the leading edge of the wind turbine blade.

Abstract: A wind turbine blade comprising a system for monitoring the deflection of a wind turbine blade is described. The system comprises a wireless range-measurement system, having at least one wireless communication device located towards the root end of the blade and at least one wireless communication device located towards the tip end of the blade and internally within the blade body. Radio absorbing material is arranged internally in the blade body in the wireless communication path between the root-and tip devices.
