    Abstract: A dielectric waveguide (DWG) has a longitudinal core member with a first dielectric constant value surrounded by a cladding with a cladding dielectric constant value that is lower than the first dielectric constant value. A first port of a signal divider is connected to receive a signal from the DWG. A second port and a third port are each configured to output a portion of the signal received on the first port, wherein the first and second port are approximately in line and the third port is at an angle to a line formed by the first port and the second port. The first port and second port have a core member with the first dielectric constant value, and the third port has a core member with a second dielectric constant value that is higher than the first dielectric constant value.
