Abstract
This paper presents a novel concept for two-dimensional (2-D) beam steering using a planar printed antenna. The concept is based on the theory of holographic antennas and is using frequency scanning in one dimension and phase scanning in the second dimension. A short review on the principle of holography and holographic antennas is given, as well as measurements and simulations of a 20 GHz printed holographic antenna. Finally, the novel beam-scanning concept is explained and verified by electromagnetic simulations of a 90 GHz unidirectional 2D beam steering antenna.
