Abstract

Mobile wireless networks of the future will be expected to function in highly diverse environments from dense foliage to dense urban settings. Under these conditions, the phenomenon of multipath fading will be a problem Here we describe a new technique to eliminate multipath fading in such wireless networks. Our technique is based on a free parameter in the design of Fresnel zone plate antennas, a type of reference phase. The technique exploits our ability to control relative phase between desired signals arriving in the antenna beam and of undesired multipath signals coming from outside of the beam direction. By control over relative phase, we can reduce the degree of fading to arbitrarily small values.
