A compact 3D-microwave holographic pointer system using a size reduced microstrip planar array

A compact system for a three dimensional (3D) pointer (mouse) is possible by combining microwave holography with microstrip antenna arrays to enter 3D coordinates of a point in space into computer memory. To reach the practical reduced size system, new solutions are proposed in both the receiving planar array antenna for constructing the point hologram image and the holographic algorithms for reconstructing the microwave hologram.
