Broadband mmWave Splitters Based on Dielectric Waveguides

In this contribution, we are presenting mmWave signal splitters with equal and unequal splitting ratios. Based on a dielectric waveguide concept, the proposed components are cost effective, easy producible, and suitable for ultra broadband operation. Next to fundamental considerations, we are presenting 3D-EM simulations and measurement results of manufactured splitters that show excellent properties within the frequency range from 70 to 90 GHz.
