Abstract
A feed line structure (1), especially integrated with a stationary array of antenna elements so as to enable adjustment of the direction of the beam radiated from the array. The feed line structure comprises a feed conductor line pattern (3) disposed on a fixed carrier plate (2) at a distance from and in parallel to a fixed ground plate (4), and a movable dielectric plate (5) located therebetween. The feed line pattern (3) is elongated in the same direction (A) as the movement direction of the dielectric plate (5). The propagation velocity of the signal components is reduced by the dielectric plate (5), whereby a controlled phase difference between the various signal components is obtained.
