Fiber optic data distribution for phased array antenna

摘要

A fiber optic data distribution system is disclosed for distribution of the phase shift commands to an electronically steered antenna array. Novelties include the fan-out of a single bundle to multiple receptors, equalization of optical path for precise synchronization, the use of the RF active side of the antenna for data distribution, the use of the antenna radome as support structure for the fiber optics, and an optical reflector to divert light from the plane of the radome to the transmit/receive element.
