Abstract
A self-supporting field director for use in heating an article in a microwave oven is characterized by a plurality of vanes, each vane extending radially outwardly from a central axis and being angularly adjacent to two other vanes. The vanes are supported by a slotted central support member. Each vane has a substrate formed from an electrically non-conductive material. A portion of at least one of the first and second major surfaces is covered by an electrically conductive material.
