Abstract
An improved microwave applicator includes a frequency tuner discoupled from an input power coupling tuner. The frequency tuner includes parallel elongated dielectric bars axially adjustable in a dielectric-filled waveguide. A central passageway space is provided between the dielectric bars for incorporation of an input coupling tuner in the form of a magnetic loop assembly. The magnetic loop assembly includes a metal loop connected to a metal block and means for axially adjusting the position of the loop assembly within the central passageway space between the elongated dielectric members. Frequency and input coupling tuning controls, as well as the microwave input connector, are located behind the closed end of the waveguide applicator to facilitate optimization of mutual positioning of multiple applicators.
