Design of an electronic beam forming network for phased array applications

摘要

A phased array antenna element design and method of using same is disclosed wherein the antenna elements are each provided several signals containing phase, and amplitude information for controlling a beam transmitted or received. The signals are mixed within each antenna element to produce RF signals for transmission or for use as filtering signals for reception. The signals are selected such that some antenna elements receive a same signal and more particularly, such that a single signal is provided to each row of the array and to each column of the array. The row and column signals are combined at elements located at an intersection of the row and column.
