SCALABLE MM-WAVE ARRAYS WITH LARGE APERTURES REALIZED BY MM-WAVE DIELECTRIC WAVEGUIDES

摘要

Direct signal distribution at mm-wave frequencies is provided by using dielectric waveguides for passive coherent distribution. The relevant distribution path lengths at mm-wave frequencies are short enough that accumulated phase error is not a significant problem. Meanwhile, the dielectric waveguides provide low loss and substantial immunity to electrical interference, thereby avoiding the main disadvantages of direct signal distribution in RF systems.
