Abstract
Aspects of the subject disclosure may include, for example, a coupling device includes a circuit that receives a signal. At least one passive electrical circuit element generates an electromagnetic field in response to the signal. A portion of the electromagnetic field is guided by a surface of a transmission medium to propagate as a guided electromagnetic wave longitudinally along the transmission medium. Other embodiments are disclosed.

A transmission device comprising:
- a transmitter that generates a signal;
- and
- at least one passive electrical circuit element, coupled to the transmitter, that generates an electromagnetic field in response to the signal, wherein the signal has a wavelength;
- wherein the transmitter and the at least one passive electrical circuit element are configured such that a portion of the electromagnetic field is bound to an outer surface of a transmission medium to propagate as a guided electromagnetic wave longitudinally along the transmission medium to facilitate wireless network connectivity to a client device via an antenna, wherein the transmission medium is without a conductor, and wherein the transmission medium is composed of a dielectric element;
- wherein the at least one passive electrical circuit element includes a first capacitor and a second capacitor that are spaced a distance apart to facilitate launching the guided electromagnetic wave longitudinally along the transmission medium, and wherein the distance apart corresponds to substantially one quarter of the wavelength.
