US Patent 10424838 Antenna structure with doped antenna body

In accordance with one or more embodiments, a communication device includes a dielectric antenna having a body of first dielectric material doped with particles of a second dielectric material. A cable comprising a dielectric core is coupled to a feed point of the dielectric antenna. A transmitter, coupled to the cable, facilitates a transmission of electromagnetic waves, the electromagnetic waves are guided by the dielectric core to the feed point of the dielectric antenna, without requiring an electrical return path.
