Claim:
1. An ablation device, comprising: a feedline including an inner conductor having a distal end, an outer conductor coaxially disposed around the inner conductor, and a dielectric material disposed between the inner conductor and the outer conductor; an elongated electrically-conductive member longitudinally disposed at the distal end of the inner conductor and having a proximal end; a dielectric junction having a distal-most end coupled to the proximal end of the elongated electrically-conductive member and a proximal end coupled to a distal end of the outer conductor, the inner conductor extending through the dielectric junction and terminating at the distal-most end of the dielectric junction; a dielectric layer coaxially disposed around at least a portion of the outer conductor and extending distally beyond the distal end of the inner conductor; and a first balun disposed around at least a portion of the outer conductor and including an electrically-conductive layer, the dielectric layer coaxially disposed around the electrically-conductive layer of the first balun.
