Patent ID: 8633784

Claim:
A contactless RF coupling device comprising: a first substrate that includes a first ground plane on one side of the first substrate and a first transmission line on an opposing side of the first substrate, the first transmission line including an enlarged first coupling member at an end of the first transmission line; and a second substrate that includes a second ground plane on one side of the second substrate and a second transmission line on an opposing side of the second substrate, the second transmission line including an enlarged second coupling member at an end of the second transmission line to transfer an electric field from the enlarged first coupling member to the enlarged second coupling member, wherein the enlarged first coupling member is an enlarged first coupling disk and the enlarged second coupling member is an enlarged second coupling disk, wherein the enlarged first coupling disk is a circular disk and the enlarged second coupling disk is a circular disk, wherein the enlarged first coupling circular disk has a diameter that is between one and ten times as great as a distance between the enlarged first enlarged coupling member and the enlarged second enlarged coupling member and the enlarged second coupling circular disk has a diameter that is between one and ten times as great as the distance between the enlarged first enlarged coupling member and the enlarged second enlarged coupling member.
