Abstract
An RF antenna assembly is to be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery. The RF antenna assembly includes a series of tubular dipole antennas to be positioned within the wellbore, each tubular dipole antenna having a pair of dipole elements, and an RF transmission line extending within the series of tubular dipole antennas. The RF antenna assembly includes a respective coupling structure between each pair of dipole elements and between the series of tubular dipole antennas, each coupling structure including a dielectric tube mechanically coupling adjacent dipole elements, and a tap connector carried by the dielectric tube and electrically coupling the RF transmission line to a corresponding dipole element.
