RF antenna assembly with dielectric isolator and related methods

摘要

An RF antenna assembly is positioned within a wellbore in a subterranean formation for hydrocarbon resource recovery. The RF antenna assembly includes first and second tubular conductors and a dielectric isolator therebetween. The dielectric isolator includes a dielectric tube having opposing first and second open ends, a first tubular connector having a first slotted recess receiving therein the first open end of the dielectric tube, and a second tubular connector having a second slotted recess receiving therein the second open end of the dielectric tube.
