The antenna assembly (12) including a first dielectric segment (284) and a second dielectric segment (274) configured to be coupled to the first dielectric segment (284) about the longitudinal axis of the antenna assembly (12). The first and second dielectric segments (284, 274) cooperatively defining a longitudinal channel extending along the longitudinal axis. The electrosurgical device (10) further comprising a feedline (110) including an inner conductor (220) disposed within the channel of the first and second dielectric segments (284, 272).
