Abstract
A radio frequency (RF) and fluid coupler is for a subterranean assembly. The assembly may have a fluid passageway therein, and may include an RF antenna and a coaxial transmission line connected thereto. The coupler may include an electrically conductive hollow body that includes electrically conductive segments connected together in end-to-end relation at respective joints to provide an outer electrical pathway to connect to the outer conductor of the coaxial transmission line. An elongate conductive member may extend within the electrically conductive hollow body to provide an inner electrical pathway to connect to the inner conductor of the coaxial transmission line. A respective dielectric pressure barrier may be between the elongate conductive member and adjacent portions of the electrically conductive hollow body adjacent each of a pair of joints to define a fluid chamber to connect to the fluid passageway. A fluid port may be connected to the fluid chamber.
