Abstract
A radio frequency (RF) applicator may be rotated during positioning within a wellbore in a subterranean formation. The wellbore may have at least one bend therein. The RF applicator may include a series of tubular conductors, and a respective bendable tubular dielectric coupler rotationally interlocking opposing ends of adjacent ones of the series of tubular conductors to define a tubular antenna. The RF applicator may include at least one RF feed conductor extending within the tubular antenna and connected to the series of tubular conductors.
