Abstract
A dual slot microwave probe for tissue ablation provides axially spaced slots producing an improved heating pattern with reduced axial extent. Degradation in this heating pattern caused by the addition of ceramic support elements and/or fluid cooling is realized through a feeding structure delivering separate sources of microwave energy to the different slots of the probe aligned with the slots of the probe.
