Abstract: A radio frequency (RF) antenna assembly configured to be positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery may include an RF transmission line and an RF antenna coupled to the RF transmission line. The RF antenna assembly may also include an adjustable balun that may include a tubular balun housing surrounding the RF transmission line and defining a space therebetween. The adjustable balun may further include an adjustable shorting body slidably movable within the space and contacting the tubular balun housing and the RF transmission line at an adjustable shorting position.

Abstract: An RF antenna assembly may include first and second tubular conductors, a dielectric isolator, and first and second electrical contact sleeves respectively coupled between the first and second tubular conductors and the dielectric isolator. The RF antenna assembly may include an RF transmission line having an inner conductor and an outer conductor extending within the first tubular conductor, and a feed structure coupled to a distal end of the RF transmission line. The feed structure may include a first radially compressible connector coupled to the outer conductor of the RF transmission line to slidably engage adjacent portions of the first electrical contact sleeve, a second radially compressible connector coupled to the inner conductor of the RF transmission line to slidably engage adjacent portions of the second electrical contact sleeve, and a dielectric tube coupled between the first and second radially compressible connectors.
