OPTICAL FEED NETWORK FOR PHASED ARRAY ANTENNAS

摘要

An optical feed network for a phased-array antenna may comprise a phase-based feed network that may include electro-optical phase shifting.

主权项

1. An optical feed network comprising:
a polarization combiner configured to receive two optical signals and to provide a combined output; a splitter unit coupled to the polarization combiner to receive the combined output and configured to split the combined output into an. integer number of channel signals; and a plurality of electro-optical phase shifting elements configured to phase modulate the channel, signals to produce phase-modulated signals.
