1. An antenna system comprising:
- an antenna;
a communications interface that receives a communication signal that includes data;
a transceiver, coupled to the communications interface, that generates an electromagnetic wave based on the communication signal to convey the data in accordance with at least one selected electromagnetic (EM) mode, wherein the electromagnetic wave is at non-optical frequencies and wherein the at least one selected EM mode is selected by the transceiver from a plurality of EM modes that include;
a non-fundamental EM mode, and a fundamental EM mode; and
a coupler, coupled to the transceiver, configured to receive and couple the electromagnetic wave to an outer surface of a transmission medium that facilitates wireless transmission via the antenna, wherein the coupler includes a conductive ring and a tapered collar that surrounds the transmission medium, wherein the conductive ring guides the electromagnetic wave to the tapered collar, and wherein the tapered collar couples the electromagnetic wave to the transmission medium for propagation along the outer surface of the transmission medium according to the at least one selected EM mode.

Abstract
Aspects of the subject disclosure may include, for example, a coupler that includes a tapered collar that surrounds a transmission wire. A coaxial coupler, that surrounds at least a portion of the transmission wire, guides an electromagnetic wave to the tapered collar. The tapered collar couples the electromagnetic wave to propagate along an outer surface of the transmission wire. Other embodiments are disclosed.
