Abstract
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).

Claim 1
Independent Claim
197 words
A method for selecting a phase shift along an electrical transmission line of fixed physical length and in the form of an electrical connector comprising, an elongated conductive shell of fixed length, electrical connector coupling means at the ends of the shell for coupling the shell along a corresponding electronic transmission line, an elongated passage extending through the shell, an elongated electrical conductor of fixed length extending through the passage, and electrical contact means at the ends of the conductor for electrical coupling of the conductor along the corresponding electronic transmission line, the method comprising the steps of: selecting a first dielectric means and a second dielectric means directly together in series for concentrically encircling the conductor, varying selectively an electrical length of the transmission line while maintaining a fixed physical length of the transmission line by selectively varying the proportion of the individual physical lengths of the first dielectric means and the second dielectric means in relation to a constant sum of the individual physical lengths, supporting the conductor concentrically within the passage by a third dielectric means and encircling concentrically the conductor with the first dielectric means and the second dielectric means within the passage.
