A self-supporting field director structure for use in heating an article in a microwave oven is characterized by a vane array comprising a plurality of V-shaped vane doublets, wherein each vane doublet itself comprises a first and a second vane. Each vane extends radially outwardly from the central axis. Each vane has a substrate formed from an electrically non-conductive material, with a portion of each vane being electrically conductive. A vane support structure is attached to the vane array.
