1. A dielectric antenna, comprising:

  • a dielectric antenna body having a longitudinal axis and an aperture; and

    a feed point configured to receive first electromagnetic waves propagating along a core without requiring an electrical return path;

    wherein the first electromagnetic waves propagate through the dielectric antenna body and generate free-space wireless signals from the aperture of the dielectric antenna body in accordance with a hollow-boresight antenna beam pattern having a null in a direction corresponding to the longitudinal axis of the dielectric antenna body.
