1. A method of transmitting signals on a superluminal antenna, comprising:
- providing an array of superluminal antenna elements including dielectric radiator elements arranged such that neighboring dielectric radiator elements have their edges touching;
providing varying voltage signals on each of the array of superluminal antenna elements via a signal conductor selected from a group including one of the following;
a coaxial cable, an input cable, signal conductor, or a waveguide;
for each superluminal antenna element, transmitting its respective varying voltage signal to first and second ends of its respective dielectric radiator element via a first conductive element connected to a conductive impedance transition and a second conductive element connected to a sleeve balun; and
wherein the varying voltage signals induce a polarization current to move inside a dielectric volume formed by the touching dielectric radiator elements of the array of superluminal antenna elements.

Abstract
A superluminal antenna element integrates a balun element to better impedance match an input cable or waveguide to a dielectric radiator element, thus preventing stray reflections and consequent undesirable radiation. For example, a dielectric housing material can be used that has a cutout area. A cable can extend into the cutout area. A triangular conductor can function as an impedance transition. An additional cylindrical element functions as a sleeve balun to better impedance match the radiator element to the cable.
