ABSTRACT:
Precise capacitive coupling to a coil is provided by a coil form having a central winding portion for a coil and having transverse flanges at the ends of the winding portion. The flanges are shaped and dimensioned to fit in a structure or resonant cavity, and have facing grooves for receiving and holding a sheet of insulating material in a plane substantially parallel to the coil winding portion. A metallic plate of predetermined size and location is positioned on the insulating sheet, and provided with a connection to an external circuit. The metallic plate provides capacitive coupling to a coil wound on the winding portion. This coupling is of predetermined magnitude and repeatable consistency, since identical coil forms can be made to hold their respective insulating sheets and metallic plates in the same location.
