Abstract
A phase shifter (1) in the form of an electrical connector comprises; an elongated conductive shell (2) of fixed length, electrical connector coupling means (5,6) at the ends (7,8) of the transmission line, an elongated passage (3) extending through the shell (2), an elongated electrical conductor (4) of fixed length extending through the passage, electrical contact means (22,23) at the ends of the conductor (4) for electrical coupling of the conductor (4) along the corresponding electronic transmission line, first dielectric means (31) and second dielectric means (43) concentrically encircling the conductor (4) within the passage (3), a conductive sleeve (38) within the passage (3) in engagement with the shell (2), and the second dielectric means (43) is between the sleeve (38) and the conductor (4).
