A reactively steered adaptive antenna array comprising: a plurality of resonant elements arranged in a predetermined pattern; a utilization device connected to a selected one of said resonant elements having an electrical output; a plurality of reactively tuneable elements equal in number to the remaining number of resonant elements and connected thereto one reactively tuneable element to each resonant element; and a plurality of control circuits each including a synchronous detector and equal in number to the number of reactively tuneable elements and connected thereto and each control circuit having its synchronous detector connected to the utilization device to receive the electrical output therefrom, whereby the reactively tuneable element causes the resonant element connected to the utilization device signals in a phase controlled manner to effectively steer the directional response of said pattern of resonant elements.
