1. An apparatus for heating comprising:

  • an antenna including at least one convolution of conductor having an axis, said antenna being adapted for being placed near a volume to be heated with said axis roughly normal to the surface of said volume, said antenna also being adapted for receiving radio frequency current in said at least one convolution of conductor for transducing the power represented by said current to a radio frequency field, said radio frequency field having a null on said axis in the vicinity of said at least one convolution of conductor;

    reflecting and supporting means electromagnetically and mechanically coupled to said at least one convolution of conductor for directing said radio frequency field towards said surface and for supporting said at least one convolution of conductor; and

    temperature signal sensing means mechanically coupled to said reflecting and supporting means for being supported at a position centered on said axis for sensing the temperature of said surface, whereby said temperature signal sensing means is located at a position of low radio frequency field intensity and has little effect on, and is little affected by, said radio frequency field.
