Kurzbeschreibung (Abstract)
Three realisations of 35 GHz reflect arrays with fixed beam are presented. The first single-layered reflect array uses variable patches as phase-shifting element and serves as reference. The second one, employing patches of variable size loaded with variable length slots in the ground plane, and the third one, a double-layered reflect array using stacked patches of variable size, are designed to achieve higher bandwidth. In the second part of the paper a novel concept for a tunable reflect array unit cell using liquid crystals is presented and verified. Measurements performed in a waveguide simulator were able to demonstrate 300/spl deg/ phase tunability of a unit cell, by applying voltages up to 40 V.
