Abstract:
1. A bandgap surface for use in a transition module, the surface comprising: a ground plane; a capacitive layer including a plurality of capacitive elements arranged within a common plane, and spaced apart from said ground plane; said plurality of capacitive elements including a first capacitive element having a first shape and located at an axial center of the capacitive layer; said plurality of capacitive elements including a plurality of second capacitive elements each having a second shape, the second shape being different than the first shape of the first capacitive element, and the plurality of second capacitive elements being arranged in polar configuration around the first capacitive element and with uniform spacing from the first capacitive element, and so as to form a plurality of concentric bands all arranged about the first capacitive element; and a plurality of electrically conductive vias disposed within a dielectric layer of material that conductively couple said ground plane to each of said plurality of capacitive elements.
