Abstract
An apparatus for coupling electromagnetic signals from a signal transfer locus for electromagnetic transfer with a proximal medium includes: (a) An antenna element presenting elements in a spaced parallel relation with an antenna plane on a first dielectric substrate. (b) A transmission structure including a second dielectric substrate parallel with a transmission plane perpendicular with the antenna plane and including a slot line structure and a ground plane. The slot line structure has a first end proximal with the signal transfer locus and a second end within electromagnetic coupling range of the antenna element. The ground plane cooperates with the slot line structure and the second dielectric substrate to effect transmission of electromagnetic signals between the first end and the second end. (c) A coupling aperture traverses a respective antenna element adjacent each respective second end in register with the respective second end.
