    摘要: An antenna arrangement (210) for generating an electric field inside a process chamber (202) through a window (212). Generally, the antenna arrangement (210) comprises an outer loop (610), comprising a first outer loop turn (618) disposed around an antenna axis (614), an inner loop (606), comprising a first inner loop turn (616) disposed around the antenna axis (614), wherein the inner loop (606) is closer to the antenna axis (614) than the outer loop (610) is to the antenna axis (614) in each azimuthal direction, and a radial connector (640) radially electrically connecting the outer loop (610) to the inner loop (606), wherein the radial connector (640) is placed a large distance from the window (212).
