Abstract: There is provided a phased array antenna comprising a plurality of antenna elements (12) and switching circuitry configured to switch the phased array antenna to an inactive mode. The switching to the inactive mode comprises the switching circuitry connecting random or pseudo-random impedance elements (20) to the antenna elements to reduce the peak backscatter level of the phased antenna array.
