Abstract

An antenna control system in which various antenna elements in a vertical row are coupled by fixed transmission lines to a central feeding point for a common signal. Adjustment of the phase of the common signal is achieved by means of a linearly movable slide having dielectric body portions influencing the signal velocity along said fixed transmission lines. Further, an electrical motor is used for linearly displacing said movable slide with said dielectric body portions.
