1. A coupling device comprising:
- a receiving portion, that receives, from a transmitting device, a radio frequency signal conveying data;
an electromagnetic coupler, that electromagnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is guided by a surface of the transmission medium; and
a dielectric portion that secures the transmission medium adjacent to the electromagnetic coupler and provides a spacing between the electromagnetic coupler and a reflective plate that reduces electromagnetic emissions from the electromagnetic coupler, wherein the spacing corresponds to substantially one-half of a wavelength of the radio frequency signal.

Abstract
Aspects of the subject disclosure may include, for example, a coupling device including a receiving portion that receives a radio frequency signal conveying data from a transmitting device. A magnetic coupler magnetically couples the radio frequency signal to a transmission medium as a guided electromagnetic wave that is bound by an outer surface of the transmission medium. A cap includes a dielectric portion that secures the transmission medium adjacent to the magnetic coupler and a reflective plate that reduces electromagnetic emissions from the magnetic coupler. Other embodiments are disclosed.
