BEAMFORMING USING A BACKPLANE AND PASSIVE ANTENNA ELEMENT

摘要

An active antenna element (120) to transmit and/or receive RF (Radio Frequency) signals is positioned in relation to a backplane (130) that reflects RF signals. One or more passive antenna elements (110, 112) can be disposed on a similar side of the backplane as the active antenna element. Settings of the one or more passive antenna elements are adjusting to produc e an input/output beam pattern that varies depending on whether the at least o ne passive antenna element is reflective or transmissive. Based on this technique, an RF input output beam pattern of an antenna assembly including the backplane, active antenna element and passive antenna elements can be controlled for better reception and transmission of RF signals.
