Paper Abstract

Feasibility of space-fed optical beam forming networks for use on board satellite C-band multi-beam phased-array antennas is addressed in this paper. Two optical space-fed BFN architectures have been investigated: one using optical fibers as delay lines to simulate the required microwave phase shifts at the feed array elements and the other formed by reducing the microwave BFN to optical dimensions and then converting, in a 1:1 correspondence, the optical phase shifts to the microwave equivalent. BFN system design, trade-off and performance are evaluated for payload weight, size and power requirements.
