Abstract

Broadband, free beam squinting and large scanning angle are essential for many applications. In views of these requirements, a tunable optical beam-forming for millimeter wave is proposed and demonstrated experimentally based on dispersive prism and variable optical delay line (VODL). Experiments are implemented with 1×4 antenna array operating at Ka band. Two beams are produced simultaneously for amplitude comparison direction finding. By tuning the relative delay of four VODLs, the beams can sweep across -30°~30°.
