Abstract

In accordance with one or more embodiments, a dielectric coupler includes a neck portion configured to receive a first electromagnetic waves from a hollow waveguide. A plurality of arms is configured to generate, responsive to the first electromagnetic waves, second electromagnetic waves along a surface of a transmission medium, wherein the plurality of arms each end at differing azimuthal orientations relative to the transmission medium and wherein the second electromagnetic waves propagate along the surface of the transmission medium without requiring an electrical return path. A splitter portion is configured to split the first electromagnetic waves among the plurality of arms.
