1. An antenna system for tissue ablation, the antenna system comprising:
an energy transmission member;
an antenna body coupled to the energy transmission member;
a fluid source; and
a choke member including a choke body and a choke connector electrically coupling the choke body to the energy transmission member, the choke connector in direct contact with fluid from the fluid source and forming a delivery path for the fluid between the choke body and the energy transmission member, wherein the choke connector comprises a plurality of conductive beads extending between the energy transmission member and the choke body, wherein each conductive bead of the plurality of conductive beads is coupled to the choke body independent of each other conductive bead of the plurality of conductive beads.
