Dielectric-filled surface-mounted waveguide devices and methods for coupling microwave energy

A method for fabricating a radio-frequency (RF) waveguide, the method comprising:

• forming or providing a dielectric block having a first edge that joins a mounting surface and a first adjacent surface;
• and
• covering the dielectric block with a conductive material to define a wrap-around opening that exposes the dielectric block along the first edge, the wrap- around opening including a strip on the first adjacent surface along the first edge and a strip on the mounting surface along the first edge.

A radio-frequency (RF) device comprising:

• a substrate configured to receive one or more components;
• and
• an RF waveguide mounted on the substrate, the RF waveguide including a dielectric block having a first edge that joins a mounting surface and a first adjacent surface, the RF waveguide further including a conductive coating that substantially covers the dielectric block, the conductive coating defining a wrap-around opening that exposes the dielectric block along the first edge, the wrap-around opening including a strip on the first adjacent surface along the first edge and a strip on the mounting surface along the first edge.
