Abstract

In a phase-shift control for a phased array antenna the antenna modules are arranged in rows and columns. The phase shift control is provided with central computing means for calculating from the beam direction to be determined and the frequency of the energy emitted, the terms in the mathematical expression for the phase setting for the separate phase shifters in the antenna modules, which terms are the same for all phase shifters, and a computing chip present in each antenna module for deter­ mining the desired phase setting from the terms determined by the central computing means and the position of the separate phase shifters in the array.
