Abstract
A system for transmitting broadband data signals between a mobile element and a fixed control station utilizes a fixed hollow tube forming a fixed waveguide for microwaves provided with a continuous longitudinal center slot and a movable hollow tube carrying the moving element and forming a moving waveguide for microwaves. The movable hollow tube has a longitudinal axis which forms an angle with the longitudinal axis of the fixed hollow tube and is equipped with an electric antenna penetrating into the center slot of the fixed hollow tube and coupled to the movable hollow tube via a coaxial cable-to-waveguide transition. The movable hollow tube is also provided with an elongated center slot parallel to its longitudinal axis and cooperates with a transmit and/or receive antenna for transmitting the microwave radiation to the mobile element linked thereby with the fixed control station.
