Guided-wave transmission device with diversity and methods for use therewith

摘要

Aspects of the subject disclosure may include, for example, a transmission device that includes a first coupler that guides a first electromagnetic wave to a first junction to form a second electromagnetic wave that is guided to propagate along the outer surface of the transmission medium via one or more guided-wave modes. These mode(s) have an envelope that varies as a function of angular deviation and/or longitudinal displacement. Other embodiments are disclosed.

主权项

1. A transmission device comprising:
a transmitter that generates a first electromagnetic wave conveying first data; and a first coupler, coupled to the transmitter, that guides the first electromagnetic wave to a first junction for coupling the first electromagnetic wave to a transmission medium at a first azimuthal angle to form a second electromagnetic wave that is guided along an outer surface of the transmission medium via at least one guided-wave mode, wherein the second electromagnetic wave has an envelope that varies as a function of angular deviation from the first azimuthal angle, wherein the function has a local minimum at a first angular deviation from the first azimuthal angle, and wherein a third electromagnetic wave propagates along the outer surface of the transmission medium in a direction opposite to the first electromagnetic wave and conveys second data; and a second coupler guides the third electromagnetic wave from a second junction coupling the third electromagnetic wave from the transmission medium at the first angular deviation from the first azimuthal angle to form a fourth electromagnetic wave that is guided to a receiver.
