Abstract
A dielectric waveguide may be manufactured by forming a set of parallel channels in a planar sheet that has a lower dielectric constant value. The set of channels is then filled with a material having a higher dielectric constant value. The planar sheet is sliced into a plurality of strips that each contain one or more of the channels.
Claims6
A sub-terahertz radio signal dielectric waveguide comprising:
- (a) an elongate, rectangular core member of dielectric material having a first dielectric constant for conducting sub-terahertz radio signals, the core member having rectangular dimensions for conducting the sub-terahertz radio signals;
- and
- (b) cladding material surrounding the core member, the cladding material having a second dielectric constant less than the first dielectric constant;
- and
- (c) an interface region formed of a metallic waveguide at one end of the core member, the metallic waveguide having one end connected to the core member and another end distant from the core member.
