Abstract
An electronically scanned antenna system includes a plurality of array elements and a control system. Each array element has a plurality of reflecting components capable of reflecting an electromagnetic wave incident thereon. Each reflecting component, in turn, is interconnected to at least one reflecting segment by at least one switch. In this regard, when the switches are in a closed state the respective reflecting segments are electrically coupled to the respective reflecting components to thereby alter a reflective geometry of the respective reflecting components. The control system is capable of controlling the switches to thereby control the array elements to provide a desired degree of phase shift to a signal reflected from the antenna. Advantageously, the control system is capable of controlling the switches of one reflecting component at the same time the control system controls corresponding switches of other reflecting components.
