Abstract
A phased array antenna tile which is steered by microelectromechanical system (MEMS) switched time delay units (TDUs) in an array architecture which reduces the number of amplifiers and circulators needed for implementing an active aperture electronically scanned array antenna so as to minimize DC power consumption, cost and mass of the system, making it particularly adaptable for airborne and spaceborne radar applications.
