Abstract (en)
A phased array antenna comprises several antenna elements , a signal feed entry from or to which a signal is transmitted to or from the several antenna elements , and for each antenna element a corresponding phase shifting device , whereby the phase difference of each signal that is transmitted from the signal feed network to the respective antenna element or that is transmitted from the respective antenna element to the signal feed network is modified by the corresponding phase shifting device (5) in order to adjust the superposition of each signal according to the preferred direction of radiation of the phased array antenna . For each phase shifting device (5) a bias voltage is applied via two bias voltage electrode lines (16, 17) that are connected to a bias voltage driver (12). The bias voltage driver (12) comprises several output channel terminal pairs (15) with two output channel terminals (13, 14) whereby the bias voltage driver (12) is able to apply a tunable output channel voltage difference to each terminal pair (15). The two bias voltage electrode lines (16, 17) of each phase shifting device (5) are connected to a respective terminal pair (15).
