摘要： An arrangement for beam forming and control of a transmitter radiating in the RF range comprises an input for feeding the RF transmitting signal RFin, a feeding network electrically connected with the input, a plurality of radiator elements, a plurality of phase shifters for receiving signals from the feeding network and for causing phase displacements for the signals before the transmission to the radiator elements, and a controller for controlling the phase displacement caused by the phase shifters. A circuit is assigned to the input of the transmitting antenna for converting the momentary phase of the transmitting signal to a digital word of a definable word length and for feeding the digital momentary phase to the feeding network. Each phase shifter comprises an adder for linking the momentary phase fed by the feeding network with a definable digital phase value generated and fed by the controller, and a circuit for converting the digital output value of the adder to an analog signal. The controller has a set of outputs which are connected with the phase shifters by way of a corresponding set of connection lines, before the transmission to the phase shifters. A definable gradient is superposed on the phase values for generating a phase difference between the phase values at the outputs of the controller.
