Claim:
1. A mm-wave antenna apparatus with beam steering function comprising: a Butler Matrix feeding network having a plurality of outputs; a plurality of power combiners, each power combiner having N outputs and one input configured to receive a respective output from the Butler Matrix feeding network, wherein each power combiner is configured to apply equal phase and power to a phase distributed output signal generated by the Butler Matrix feeding network and generate N processed signals; and a plurality of millimeter wave switched beam planar antenna arrays having at least 1.5 GHz of bandwidth and located on a top low loss dielectric substrate, wherein each antenna array has N elements configured to receive the N processed signals from the N outputs of each respective power combiner, and wherein each antenna array is configured to obtain direct and narrow width beams from the N processed signals combined by each of the power combiners, wherein the apparatus is integrated in a multi-layer printed circuit board including:
