1. A communication device, comprising:
- a dielectric antenna including a dielectric body and a dielectric feedline, the dielectric feedline extending from the dielectric body along an axis to a feed point at a first end of the dielectric feedline, the dielectric feedline having a uniform cross-section along the axis between the dielectric body and the feed point at the first end of the dielectric feedline, and the dielectric body having a non-uniform cross-section along the axis;
a conductive material disposed on at least a portion of an outer surface of the dielectric antenna; and
a dielectric core, the dielectric core having a second end that is coupled to the feed point of the dielectric feedline at the first end of the dielectric feedline, the dielectric core facilitating guiding electromagnetic waves to the feed point of the dielectric feedline at the first end of the dielectric feedline.

Abstract
Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.
