Polarization current antennas that generate superluminal polarization current waves having acceleration and related methods of exciting such antennas

摘要

Polarization current antennas comprise a dielectric radiator that extends along a z-axis, polarization devices that are positioned adjacent the dielectric radiator along the z-axis that are configured to polarize respective portions of the dielectric radiator and a feed network that is configured to excite the polarization devices with an RF signal to generate a polarization current wave that propagates in the z-axis direction through the dielectric radiator, with acceleration, at (1) a first variable speed that does not decrease as the wave moves along a first portion of the dielectric radiator and that does not increase as the wave moves along the remainder of the dielectric radiator, (2) a second variable speed that does not decrease as the wave moves along the entirety of the dielectric radiator or (3) a third variable speed that does not increase as the wave moves along the entirety of the dielectric radiator.
