Abstract :
Folded reflectarray antennas can provide a good solution for millimeter-wave systems requiring compact, low-cost antennas, e.g. in automotive applications. This contribution investigates different approaches of such antennas with rectangular and composite reflecting elements. Special emphasis is put on gain and antenna loss mechanisms, including increased beam-width and sidelobe level as well as metallization losses.
