Abstract
A folded reflectarray antenna is presented which is able to scan its beam in two dimensions. The antenna is based on the bifocal approach with phase angle adjustments on a top and on a bottom reflector. Seven feeds are used to switch between different beams in one plane, and the backside reflector is tilted to scan in the orthogonal direction. For good performance, top and bottom reflector are designed is a special way. A sample antenna has been built and tested at 77 GHz.
