<P>PROBLEM TO BE SOLVED: To provide a system for measuring an impedance in a microwave energy delivery system. <P>SOLUTION: A microwave system calibration apparatus includes an antenna portion configured to deliver microwave energy; a transmission line portion configured to receive a microwave energy signal from a microwave source and to selectively deliver the microwave energy signal to the antenna portion; and a switching mechanism connected between the antenna portion and the transmission line portion, configured to electrically disconnect the transmission line portion from the antenna portion in a first condition and further configured to connect the inner conductor to the outer conductor in a second condition. The transmission line includes an inner conductor having a length, an outer conductor concentrically surrounding the inner conductor along the length partially and a dielectric material separating the inner and outer conductors. At least one of the inner conductor and the outer conductor is electrically connected to the antenna. <P>COPYRIGHT: (C)2010,JPO&INPIT |
