Document Type and Number:
Japanese Patent JP2003505112
Kind Code:
A
Abstract:
A microwave applicator for applying electromagnetic radiation at microwave frequency includes a coaxial input for a microwave signal input and a waveguide for receiving and propagating the microwave signal input. Dielectric material is positioned within the waveguide and extends beyond the waveguide to form an antenna for radiating microwave energy. The coaxial input has direct in-line transition to the dielectric-filled waveguide. Preferably, this direct in-line transition is achieved by the central conductor of the coaxial input extending axially centrally into the waveguide so as to excite microwaves in the waveguide. A lateral conductor extends radially from the central conductor to assist the launch of the microwaves into the waveguide. Preferably, the applicator includes a temperature sensor which is directly connected to the coaxial input.
