Abstract

A coupling frame to provide structural support and electrical functionality includes a plurality of conductive frames spaced from each other and having predetermined gaps. A plurality of conductive sheets are electrically connected to the different places of the inside surface of the conductive frames and an insulating frame fills in the predetermined gaps. Each conductive frame and the insulating frame are annular structures. The insulating frame extends inwardly to partially cover the plurality of conductive sheets. A method for making the coupling frame is also provided.

Claims
