Abstract
The coupling of radio signals, to and from the surface of a conductive body and to and from associated radio apparatus is optimized by adding, proximate to the edge of an opening (such as a window) in the body, a closed loop of relatively highly conductive material, such as copper, and coupling said radio signals to said associated radio apparatus through a plurality of interconnected adjacent loops proximate to said closed loop to maintain proper proportion of E fields and H fields in the signals fed to associated radio apparatus.
