Abstract
In accordance with one or more embodiments, a communication device includes a dielectric antenna having a longitudinal axis, a feed point and an aperture. A cable comprising a core is coupled to the feed point of the dielectric antenna. A transmitter, coupled to the cable, facilitates a transmission of first electromagnetic waves to the feed point of the dielectric antenna, the first electromagnetic waves guided by the core. The first electromagnetic waves propagate along the core without requiring an electrical return path, and the first electromagnetic waves generate free-space wireless signals from the aperture of the antenna in accordance with a hollow-boresight antenna beam pattern.
