Integrierte planare Millimeterwellenantenne mit hohem Gewinn
… center elements of the sub-arrays are coupled by slots to the waveguide network. Short planar strip lines accomplish the further power partition within the sub-arrays. The waveguide network is milled out of a flat aluminum block. The antenna substrate serves thereby as cover for the waveguide …

Switched aperture surface current measurements
The measurement of induced surface currents on antennas, scatterers, and other structures is important for a variety of reasons, including in-situ measurements and validation of simulated results. Techniques for measuring the complete vector nature of surface currents (magnitude, direction, and …
