Abstract

The radiated beam of an electronically steered microwave phased- array antenna is steered by controlling the relative phase between successive radiating elements of the array. Fiber-optic delay lines offer a lightweight, compact solution to accomplish truetime-delay steering of these antennas. By using a fiber-guided lightwave as the carrier for microwave signals that drive the radiating elements, we realized an optical beam-forming network that was nondispersive over multiple microwave bands.
