1. An ablation device, comprising:
- a feedline including an inner conductor, an outer conductor, and a dielectric material disposed between the inner and outer conductors;
a radiating section operably coupled to a distal portion of the feedline; and
a sleeve portion electrically coupled to the inner conductor, the sleeve portion disposed at a distal portion of the radiating section and around at least a portion of the outer conductor, the sleeve portion configured to move relative to the outer conductor to adjust a length of the radiating section.
