Enhancing operation of laminate waveguide structures using an electrically conductive fence

A system operative to enhance electrical coupling between a probe and a laminate waveguide structure, comprising:

• a printed circuit board comprising at least a first and a second laminas;
• a probe printed on a lamina belonging to the printed circuit board, said probe operative to generate millimeter-waves;
• a laminate waveguide structure embedded through at least the first and second laminas and comprising a primary electrically conductive surface operative to capture and guide millimeter--waves generated by the probe;
• and
• an electrically conductive fence, embedded inside said printed circuit board and located outside the laminate waveguide structure, said electrically conductive fence operative to reflect millimeter-waves, which escape said laminate waveguide structure due to leakage associated with said primary electrically conductive surface, back toward said laminate waveguide structure, thereby enhancing electrical coupling between said probe and said laminate waveguide structure.

A method for enhancing propagation of millimeter-waves inside a laminate structure waveguide, comprising:

• leaking millimeter-waves by a laminate waveguide structure embedded inside a printed circuit board;
• and
• reflecting, by an electrically conductive fence embedded inside said printed circuit board, said millimeter-waves back into said laminate waveguide structure;
• wherein:
• (i) said laminate waveguide structure comprises a primary electrically conductive surface operative to guide millimeter-waves through said laminate waveguide structure, (ii) said electrically conductive fence is located outside said laminate waveguide structure and in close proximity to said laminate waveguide structure, and (iii) said leaking is clue to a limitation associated with said primary electrically conductive surface,
