System for controlling a phase array antenna

A system for controlling a phase array antenna, the system comprising:

• a plurality of compensation units (2), wherein each compensating unit (2) is associated to an individual radiating element (30) of the phase array antenna, wherein each compensation unit (2) comprises:
• a phase slope control module (10) configured to control the phase slope of a radio frequency (RF) signal, wherein the phase slope control module (10) comprises a no-delay line comprising a first variable gain amplifier (11) for outputting a non-delayed signal and a delay line comprising a second variable gain amplifier (12) and a delay line element (13) for outputting a delayed signal, wherein the gain of the first amplifier (11) and the gain of the second amplifier (12) are interrelated forming an asymmetric relationship therebetween, so that the greater the gain of the first amplifier, the smaller the gain of the second amplifier, and vice versa;
• a phase shifter (20) configured to control the phase shifting of a RF signal, wherein the phase shifter (20) and the phase slope control module (10) are interconnected and coupled to the individual radiating element (30).
