Abstract:
An apparatus for coupling electromagnetic signals for electromagnetic transfer with a medium proximal with the apparatus; said electromagnetic signals being presented at a signal transfer locus; the apparatus comprising:(a) an electromagnetic antenna element proximally situated with respect to said medium; said antenna element presenting at least two generally planar antenna elements in a spaced substantially parallel relation with an antenna plane on a generally planar first dielectric substrate; (b) a transmission structure; said transmission structure including a generally planar second dielectric substrate substantially parallel relation with a transmission plane; said transmission plane being substantially perpendicular with said antenna plane; said second dielectric substrate bearing a slot line transmission structure on a first face and bearing a ground plane structure on a second face; said slot line transmission structure having a first signal coupling end proximal with said signal transfer locus and a second signal coupling end proximal with said antenna element; said second signal coupling end being within electromagnetic coupling range of said antenna element; said ground plane cooperating with said slot line structure and said dielectric substrate to effect electromagnetic transmission of said electromagnetic signals between said first signal coupling end and said second signal coupling end; and (c) a coupling structure; said coupling structure presenting a coupling aperture traversing a respective said antenna element of said at least two antenna elements adjacent said second coupling end; said coupling aperture being substantially in register with said second coupling end.
